Romford MP Andrew Rosindell has given Andrea Leadsom his backing to become the next leader of the Conservative party and Prime Minister.

Both MPs campaigned for Brexit.

Mr Rosindell tweeted “Delighted to be backing @andrealeadsom to be next Leader & PM. Integrity, conviction and strong leadership. #Leadsom4Leader #FreshStart” on Sunday.

Mrs Leadsom is a 53-year-old former banker and fund manager. She was one of the stars of the Leave campaign appearing alongside Boris Johnson in a television debate.

She has told Sky News: “My personal view very genuinely is the next leader is someone who has to deliver on the promise of the referendum because they can see the huge advantages and they believe in them. I think it’s very difficult for somebody who campaigned to stay in, who thinks that there will be disaster if we leave to suddenly turn it around and start believing we can make a go of it.”

David Cameron announced his resignation on Friday June 24, just hours after the result of the referendum was announced.

Mrs Leadsom is running against Michael Gove, Theresa May, Stephen Crabb and Liam Fox.

MPs will begin voting tomorrow to whittle the contenders down to two.

The new leader will then be announced on September 9 following a vote by party members.
