Education Secretary Michelle Donelan has resigned. Donelan was only appointed on Tuesday evening to replace Nadim Zahawi after he was made chancellor.

In her resignation letter to the prime minister, she says “yesterday, I pleaded with you to do the right thing and resign for the sake of our country and our Party, both are more important than any one person”.

“I see no way that you continue in post, but without a formal mechanism to remove you it seems that the only way this is only possible, is for those of us who remain in Cabinet to force your hand”.

She says the PM has put ministers in an “impossible situation”.
