Theresa May has insisted she has "no" concerns about the mental state of the President of the United States.

The Prime Minister was asked on BBC1's Andrew Marr Show about "quite serious questions being raised by some people about his mental state. Do you think they’re serious?"

Mrs May replied: "No. As I say when I deal with President Trump what I see is somebody who is committed to ensuring that he is taking decisions in the best interests of the United States."

Mrs May comments came after Mr Trump said on Twitter that he was a "very stable genius".
