Ed Davey’s critics want headlines, but their leader’s strategy wins seats. Undermining him could help the rightwing parties into power

Will the first victim of the political conference season be the Liberal Democrats’ Sir Ed Davey? It might seem quixotic, given that he is the most successful liberal parliamentary leader in a century. Yet a meeting of Lib Dem MPs on Tuesday night could see them collect the 18 signatures needed for a confidence vote. It’s hard to see what a putsch would achieve, apart from giving the party’s opponents a stick to beat it with. That may be the point: weakening Sir Ed in an internal war of attrition so that he walks away would be easier than removing him via a no-confidence vote passed by a majority of all Lib Dem MPs.

“Never interrupt your enemy when he is making a mistake,” said Napoleon Bonaparte. With populists slipping in the polls, Lib Dem plotters should remember this, especially as Kemi Badenoch’s Conservatives are looking to advance at the Lib Dems’ expense. The Tory economic pitch is to end the 60% marginal tax rate on earnings between £100,000 and £125,000, and let couples pass on the family home plus another £1m tax-free. It’s a clear bid to win back affluent southern voters in England’s “yellow wall”.
