A minister's adviser has quit after being caught on camera discussing with an Israeli Embassy political officer how to "take down" a senior government minister.

Maria Strizzolo, a civil servant and adviser to education minister Robert Halfon, has quit her post at the Skills Funding Agency after being filmed talking about Sir Alan Duncan, Boris Johnson's deputy at the Foreign Office.

Footage taken by Al Jazeera at a London restaurant showed Shai Masot, an Israeli Embassy senior political officer, telling Ms Strizzolo that Sir Alan, who has been critical of Israel, was in his sights.

He said Sir Alan was causing a "lot of problems", and he also dismissed Mr Johnson as an "idiot".

In the footage, which has been obtained by the Mail on Sunday, Mr Masot set out the alleged extent of Israel's participation in British politics.

He told Joan Ryan, a senior Labour MP, that he had obtained more than £1 million to pay for sympathetic party colleagues to visit Israel as he mocked Jeremy Corbyn and his "weirdo" supporters.
