The former deputy prime minister has vowed to continue to promote the EU and has said Brexiteers in the Tory government have no idea what they are doing.

Mr Clegg, who resigned as leader of the Liberal Democrats following last year’s general election, campaigned strongly for Remain during the referendum.

He told Nick Ferrari on LBC: “If you look at what Trump says, or indeed if you actually look out what Farage says, or you look at what the sort of arch Corbynistas say, if you look at what supporters of Podemos say in Spain.

“If you look at a lot of populist on right and left, they are very angry on the whole.

"And they always want someone to blame. So it's either, you know, string up the bankers or it's the mainstream media or it's even worse – it's Islam or it's the Mexicans or it's Brussels. It's always someone else's fault.
