Cutting degrees to pay for more apprenticeships is plain barmy – just look at the facts and ask yourself who this is aimed at

Once upon a time, elections used to be all about kissing babies. But for parents of teenagers, this one has felt more like a smack in the teeth. Last weekend, our children were threatened with compulsory national service, for no obvious reason beyond keeping nostalgic pensioners happy. Now, just in the middle of their GCSE revision, Rishi Sunak is threatening to scrap one in eight degree places.

“You don’t have to go to university to succeed in life,” tweeted the prime minister, who to be fair is currently proving that you can go to lots of universities – he has a degree from Oxford and a master’s from Stanford – and still see your career end in failure. The money saved by slashing 130,000 supposedly “Mickey Mouse” places would, he promised, fund 100,000 apprenticeships. Though given the enduring failure to get these off the ground over the past decade, it would be unwise to bin the Ucas form just yet. Meanwhile, the education secretary, Gillian Keegan, called the apprenticeship she did at 16 her “golden ticket” but failed to mention her subsequent degree in business studies, followed by a master’s.

High Commission to meet leaders at university after currency crash in home country meant students couldn’t pay for tuition

Delegates from the Nigerian high commission in London are to meet bosses from Teesside University to discuss the treatment of a group of students who were ordered to leave the UK after failing to meet tuition repayments.

The Nigerian students were left distressed and in some cases suicidal after they were involuntarily withdrawn from their courses and ordered to leave, in what has been described as a “serious diplomatic issue”.

Tory policy would be funded by scrapping courses with high drop-out rates and low job progression

In the latest of a flurry of announcements as the Conservatives try to narrow Labour’s 20-point poll lead, the party pledged to replace “low-quality” university degrees with apprenticeships.

The brutal repression of student protests from Amsterdam to Los Angeles is exposing failings at the heart of our universities

Across the world, university students have set up encampments to protest against the humanitarian disaster unfolding in Gaza and put pressure on academic institutions and governments. Whatever one thinks of their message and of their requests, their moral indignation in the face of avoidable human suffering is one we should all be able to share.

I find it inspiring that this student movement has been spearheaded by a generation that was too quickly labelled apolitical and self-absorbed. Think about it: these students grew up in the bleak post-9/11 world, with a future foreclosed by the 2008 financial crisis and the climate meltdown. They are still reeling from two years of pandemic that have taken a heavy educational and emotional toll. Still, this generation has succeeded in organising a global movement that is coordinated, smart and humane. It deserves much better than condescension.

Plans for a radical crackdown on graduate visas that allow overseas students to work in the UK for up to two years after graduation look set to be abandoned by the prime minister after coming up against staunch opposition from cabinet colleagues.

Rishi Sunak had been considering restricting and even scrapping the graduate visa route as a way of reducing migration figures, but he is now expected to opt for more modest reforms to close loopholes and “prevent abuse” of the immigration system.

Politicians talk about tuition fees as if the students were somehow getting a good deal. In reality, they’re being shockingly exploited

Whether or not universities are at risk of going bust is often talked about like a second-order problem. Sure, it’s sad and all, but is it as serious as a local authority going bankrupt? Is anyone actually going to die if non-Russell Group universities can no longer afford to run humanities degrees? Is it the end of the world for students to leave with 150 grand’s worth of debt, instead of 80?

But then one morning, you wake up and think: enough. Successive governments have been staring an entirely predictable calamity in the face for years, doing nothing about it while ripping off an entire generation with ever greater impunity, then masking that incompetence with casual anti-intellectualism and defeatism. OK, maybe saying that out loud doesn’t do an enormous amount to help students, but not saying it makes your blood boil.

Despite a backlash from some students and alumni in the weeks leading up to Biden’s commencement address, including over the Hamas-Israel war and concerns that Biden would use the speech as a campaign event, the president’s address to the all-male school was warmly received. He used his speech to reaffirm his commitment to democracy in the wake of the January 6 insurrection, and to reiterate his call for a ceasefire in Gaza.
