Labour has accused Donald Trump’s top official, Mike Pompeo, of trying to stop Jeremy Corbyn becoming prime minister, after he was caught on tape telling Jewish leaders that he would “push back” against the party’s leadership.

In a recording leaked to the Washington Post, the US secretary of state was asked what he would do if Corbyn were to be elected as prime minister, after sustained criticism over Labour’s handling of accusations of antisemitism within the party.

The questioner said: “Would you be willing to work with us to take on actions if life becomes very difficult for Jews in the UK?” In response, Pompeo appeared to suggest that he would seek to intervene in the debate before Corbyn had a chance to become prime minister.
