Ed Davey says he is as an economist by background. And that he has been in the business world. Both these statements are indeed true. He’s got a master's in the subject. He took time out of parliament in the 1990s to be a management consultant.

But he’s probably best known for being the head of the only major UK political party that tried to stop Brexit. Five years on from the historic vote, as leader of the Liberal Democrats, he is still banging the drum that leaving the EU is bad for the economy and for the City.
