Sir Anthony Seldon believes that the former Prime Minister was able to flatter the German chancellor and in return she took a shine to him

Angela Merkel 'quite fancied' David Cameron, his biographer has claimed.

Sir Anthony Seldon believes that the former Prime Minister was able to flatter the German chancellor and in return she took a shine to him.

At the Edinburgh International Book Festival he proclaimed: 'I think she quite fancied him, actually.

'He charmed her, he knew how to flatter her. And let's face it, they're not a whole bundle of fun, the other EU leaders.'

Sir Anthony wrote Cameron at 10 with journalist Peter Snowden and the book was serialised by the Mail On Sunday.

Other extracts reveal that the relationship between Cameron and Merkel was not always sweet as they engaged in tough negotiations ahead of the EU referendum.

In a face-to-face Downing Street showdown with the German chancellor, the Prime Minister said: ‘If there’s no deal, it’s not the end of the world; I’ll walk away from the EU.’

Mrs Merkel hit back, describing Britain as ‘Europe’s problem child’. She accused Mr Cameron of acting like a ‘wrecker’ at leaders’ meetings, saying it made him ‘hated’.

The chancellor also mocked Mr Cameron’s ‘Eurosceptic vision’, saying: ‘He who has visions should go to a doctor.’
