Far-right presidential candidate’s TV debate swipe at rival backfires as people take to social media to parody it

To Flávio Bolsonaro and his publicists, it must have seemed an ingenious idea that would expose his rival’s supposed crookedness on the eve of Brazil’s presidential election.

But the far-right politician’s decision to attend a primetime television debate against his leftwing opponent, Luiz Inácio Lula da Silva, with the word “corrupto” (corrupt) written on the palm of his hand has backfired.

Far-right extremism and rhetoric is coming from activists and unvetted councillors, but party leaders who peddle fear and rage can’t escape blame

Who are the hate preachers radicalising rightwing extremists? As the head of MI5 warns that anti-migrant haters are increasingly considering terrorist attacks, it is surely a question we must ask. After all, the role of hate preachers in Islamist terrorism has long been debated.

After the London Bridge Islamist terrorist attack in 2017, Nigel Farage demanded that Sadiq Khan – “as the first Muslim mayor of London” – declare that he would do all he could “to work with the Muslim community to drive out the extremist preachers from our mosques” and to fight radicalisation in schools and prisons. More recently, he suggested that Muslim parents in the United Arab Emirates feared sending their children to study in British universities “given the risk of radicalisation here”. His colleague Suella Braverman agrees. “There should be zero tolerance for hate preachers in mosques or radicalising imams in prisons,” she says.

Whether or not Netanyahu can hold on to power, Israelis are expected to vote in a more rightwing Knesset

Four decades ago, when the extremist rabbi Meir Kahane won a single seat in Israel’s Knesset, other legislators passed a law to prevent him running again, left the chamber when he rose to speak and worked together to block discussion of his ethnonationalist proposals.

These ranged from mass expulsions of Palestinians to apartheid provisions such as segregated beaches and the criminalisation of sex between Jews and gentiles.

With support for far right politics well established across Europe, how might upcoming elections shape its future? Europe correspondents Jon Henley and Ashifa Kassam answered Reddit users’ questions about their reporting from the continent

Support for far-right parties has been growing across Europe, with radical right, populist parties in coalition governments in Croatia, Czechia, Italy and Finland, and leading in the polls in Austria, Belgium, France and Germany.

The Guardian reported this year that nearly a quarter of voters in Europe voted for far-right parties in their most recent national elections, a fivefold increase since 1995.

Exclusive: Isabella Weber prescribes a common-sense solution to poverty, inequality and fascism – making life’s essentials affordable for all

The trouble with economists, Isabella Weber believes, is they do not behave like dentists. They obsess over ideological purity and are inflexible when searching for solutions, regardless of society’s symptoms. Dentists have no such pretensions – patients have little patience for dogma when in insufferable pain.

John Maynard Keynes, Weber clarifies in the canteen of the Wissenschaftskolleg zu Berlin (Berlin’s Institute for Advanced Study), was the first to draw this dental comparison – and she is running with it. As she sees it, the symptoms could not be more severe. “The status quo for the majority is entirely unbearable,” while extreme inequality and corporate concentration has reached levels “simply incompatible with democracy” worldwide. This is exacerbated by a climate crisis that “generates massive windfall profits” for big business as the “ecological foundations of our lives disintegrate”. All the while the far right is making hay.

The Spanish prime minister has been a lonely champion of progressive values in the EU. But the polls look ominous

When it comes to risk-taking, Spain’s prime minister, Pedro Sánchez, has a formidable track record. In 2018, the Socialist party leader swept to power by triggering a no-confidence vote that unexpectedly ousted his centre-right predecessor Mariano Rajoy. He held on to it against the odds after calling a snap election in 2023, at a time when the popularity of his own party had plummeted and the far right was on the rise.

As he endures another rocky period in office, Mr Sánchez has once more rolled the dice. Last week, he announced a snap poll for November after his minority government was blocked from passing measures to ease Spain’s chronic housing crisis. The eviction of 87-year-old María del Carmen Abascal from her Madrid home sparked nationwide protests over soaring rents and prices. The outrage grew with news of her death last Wednesday. Mr Sánchez clearly hopes that campaigning on a national cause célèbre gives him a chance of winning a stronger progressive mandate next month.

Jean-Noël Barrot criticises X owner in speech attacking foreign efforts to destabilise France before 2027 election

France’s foreign minister has accused Elon Musk of using his social media platform to orchestrate “massive online harassment campaigns” against European leaders as he took aim at foreign efforts to destabilise the country before next year’s presidential election.

Speaking at an Organisation for Economic Cooperation and Development conference on Tuesday, Jean-Noël Barrot pointed to the role that social media had come to play in the global battle over democracy. “The forces seeking to undermine democracy now dominate the information landscape, where they employ tactics designed to polarise public debate,” he said.

The final season of the TV epic Babylon Berlin is taking us back to 1933. Our confidence is falling apart, but that’s where the parallels end

There is one experience we in Germany can all find mildly satisfying this autumn, as we watch the dark and terrifying final season of the hit TV series Babylon Berlin. We know everything those fearless (a few of them) or frightened (many more) and opportunistic (the majority) people on the screen do not. We know their future.

Made by the public broadcaster ARD, Babylon Berlin has run for over 10 years, brilliantly fictionalising how Germany sleepwalked into nazism and the second world war. The fifth and last season begins in January 1933 with Adolf Hitler appointed Reichskanzler.

Annual update from MI5 chief highlighted a complex cocktail that could have real-life consequences for Britain

MI5’s annual threat update covers so much ground it is easy to feel anxious. The terror threat has become more diverse, with far-right anti-migrant threats on the rise; while Iran has now firmly emerged alongside Russia as a country seeking to undertake violent and deadly plots in the UK.

“There is no law of physics dictating that rising state threats will be accompanied by diminishing terrorist threats,” MI5’s director general, Ken McCallum, said, although one of his core messages was that people and the country at large needed to focus on being more resilient. “In this new world, we should expect to be tested.”

Move from anti-immigration or anti-Muslim views to violence is ‘most marked trend’ in spy agency’s caseload over last year

Extremists with anti-migrant opinions are becoming increasingly likely to consider carrying out terrorist attacks against immigration centres and asylum hotels in the UK, the head of MI5 has warned.

Ken McCallum said a shift from radicalised rightwing sentiment to violence was “the most marked trend” in the spy agency’s caseload over the past year, contributing to a rise in the overall UK terror threat level.

If far right nationalists gain power in four big countries simultaneously, we are in for a dramatic Trumpian tilt

When it comes to Europe’s economy or its peace and security, it is obvious that decision-making has to be done largely at the European level to be meaningful. Yet electoral politics is still conducted mostly at the national level. The silver lining of this mismatch is that from country to country in Europe we have governments with different political priorities and leanings. Unlike in the US, where one presidential election can radically change the entire country’s course, as we have seen so vividly under Donald Trump’s leadership, the same drama has not so far unfolded in Europe. This may be about to change.

Pedro Sánchez rolled the dice in Spain last week, calling a snap election for next month after an unholy alliance of the conservative People’s party (PP), the far-right Vox and Catalan pro-independence party Junts blocked his big housing reform package in parliament. If the socialist prime minister, hailed by progressives globally but demonised by Europe’s right and Trump’s US, loses his election gamble, Spain could fall into the hands of a conservative/far-right coalition, which is currently ahead in the polls.

MEP Raphaël Glucksmann issues call after becoming social democrat candidate for 2027 presidential election

The European lawmaker Raphaël Glucksmann has urged the French centre left to wage an “existential battle” to prevent Marine Le Pen’s far right winning the 2027 presidential election after he was chosen as the social democrat candidate for the presidency.

“We’ve got to rid our hearts of the spirit of defeat,” Glucksmann, the founder of the small party Place Publique, said on Monday morning after his decisive win in a centre-left primary race held by the Socialist party.

Exclusive: Former Brazilian environment minister warns of destruction as far-right scion favourite to become president

The former Brazilian environment minister Marina Silva has said that if Flávio Bolsonaro becomes president he will seek to finish the “perverse project” of rampant rainforest destruction initiated by his jailed far-right father.

The Amazon was thrown into chaos during Jair Bolsonaro’s 2019-2022 presidency, when Brazil’s environment and Indigenous protection agencies were gutted and environmental criminals ran riot, causing surges in deforestation and violence.

Are we really living through ‘end times fascism’? The authors Naomi Klein and Astra Taylor think so.

In a new series from the Guardian, the pair speak to Radical Thinking with Aditya Chakrabortty in an extended interview. From Trump 2.0 and the rise of the tech billionaire to Gaza and the ongoing climate emergency, Klein and Taylor argue we are not just lurching from crisis to crisis, but are in a new and dangerous moment in history. However, they haven’t given up hope of a fightback.

Radical Thinking will be published every Saturday in the Politics Weekly feed

Extremists are on the rise globally – but UK activists have seen them off in the past in everything from football, politics, music and more. How did they do it?

Tariq Mehmood encountered the far right early – at primary school. “When white children surround you in the playground and sing, ‘God made little black people, he made them in the night, he made them in a hurry, and forgot to paint them white’, and the school doesn’t clamp down on that, then you’re living within the far right. It’s not one organisation, it’s a mass movement.”

Parties vow to challenge law in court, arguing that extra reward for those with 42% of support distorts public representation

• Europe live – latest updates

A controversial overhaul to electoral law that critics say is aimed at boosting Giorgia Meloni’s chances of clinging on to power in elections next year has been given final approval by the Italian parliament.

Meloni, the Italian prime minister, says the new system, which introduces a fully proportional model, including bonus seats for any coalition that wins the most votes, will bring about greater political stability, while opposition parties argue that it mainly serves the interests of those in power.

Little if any sign Bury Park is a place where any group might fear to tread, despite Tory MP’s comments to the contrary

From behind the counter of his chippie, Tanner Ahmed is wrestling with the notion that the regular stop-off point for fans attending Luton Town’s nearby football ground could be in a “no-go zone” for white people.

“The whole point of setting up was to cater for thousands who were coming through here every week, especially in the first year when the club was in the Premier League,” said Ahmed, affectionately known as Mr T, in the Bury Park area, a predominantly Asian district of Luton.

After a surprise first-round victory, critics suggest son of disgraced ex-president could seek to continue his father’s authoritarian project

• Flávio’s surprise first-round win highlights rapid rise of Brazil’s House of Bolsonaro

Flávio Bolsonaro, the far-right frontrunner to become Brazil’s next president, has vowed to “re-democratise” the South American country, increasing fears about a move into authoritarian rule if he wins power.

Brazil was re-democratised in the 1980s after a brutal 21-year dictatorship that Flávio’s father, the disgraced ex-president Jair Bolsonaro, has long praised.

A thriving economy, a model green transition, social advances – Spain’s PM shouldn’t be in trouble. Yet he is, and it’s a lesson for progressives everywhere

To progressives across the west, Spain has been a rare glimmer of hope in a world where far-right parties are increasingly entering government. Under Pedro Sánchez, who became prime minister in 2018, the country has combined a post-Covid economic boom with a bold green energy transition programme, and a pro-immigration stance with a principled opposition to the war agenda of Donald Trump and Benjamin Netanyahu. Yet, at the end of next month, this rare beacon of democratic progress could fall.

On Monday Sánchez called a snap general election, set for 29 November, after two decrees to address the country’s housing crisis were voted down in the lower chamber by politicians from rightwing parties. Speaking from the staircase of the Moncloa palace, Sánchez admitted that his government had not achieved all it had set out to do. “Many injustices remain to be corrected … particularly regarding inequality in public services and access to housing,” he said, adding: “To do more, we need to renew and expand public support.”
