The chief executive of Donald Trump's presidential campaign has been accused of making antisemitic remarks by his ex-wife.

It is claimed that conservative filmmaker and media boss Stephen Bannon said he did not want his daughters "going to school with Jews".

In a court statement in 2007, Mr Bannon's former wife, Mary Louise Piccard, also alleged that he had not wanted his girls to attend a top Los Angeles private school because "he doesn't like Jews and he doesn't like the way they raise their kids to be 'whiny brats'."

A spokeswoman for Mr Bannon denied the allegations. "Mr Bannon never said anything like that," she said.

Mr Bannon is the former head of Breitbart News, which has long supported Mr Trump's presidential bid.

In May, the Breitbart news site posted an article calling prominent US conservative William Kristol a "renegade Jew" for supporting an independent bid for the presidency in a "stop Trump" move.

Mr Kristol was accused of "weaken[ing] the only party that stands between the Jews and their annihilation, and between America and the forces intent on destroying her".
