UK Prime Minister Theresa May will face a vote of confidence in her leadership later on Wednesday.
Speaking outside 10 Downing Street, Mrs May said: “I will contest that vote with everything I have got.”
Mrs May said changing Conservative leader would “put our country’s future at risk and create uncertainty when we can least afford it”.
“A leadership election would not change the fundamentals of the negotiation or the Parliamentary arithmetic.
“Weeks spent tearing ourselves apart will only create more division just as we should be standing together to serve our country. None of that would be in the national interest,” she said in her statement.
