Yesterday in London Paddy Ashdown, Ming Campbell, Nick Clegg and Tim Farron came together to make the case for Europe.

Tim Farron made a pitch to young people to vote. He advised younger people not to let those older people who have gripes against modern life determine the outcome: “Do not let those who are grumpy throw away your future.” Nick Clegg said: “The Conservatives are inflicting their family row on us but it is not their families’ futures at stake. It is not their jobs at stake. Indeed, Boris Johnson and Michael Gove probably regard it as a chance for promotion in their own party.”

Paddy Ashdown accused Johnson and Gove of posing as “working class revolutionaries”: “Boris Johnson and Michael Gove driving around the country in a German bus claiming to be Karl Marx and Friedrich Engels does stretch rational credibility.” Ming Campbell argued it was vital that EU countries worked together: “Nigel Farage is a man of privilege, pretending to be on the side of the under-privileged, while dressed from the pages of Country Life”.
