South Northamptonshire MP Andrea Leadsom has announced that she is to stand for the Conservative Party leadership.
There had been speculation that the 53-year-old would back Boris Johnson instead, but she has now decided to go for the top job herself.
Leadsom is among the bookies' favourites to take over from David Cameron and is currently the 10/1 fourth favourite.
Andrea Leadsom will find out if she's made it through to the final two of the Tory leadership contest in a few hours time.
The next leader of the Conservative Party and Prime Minister must come from the Brexit camp, South Northants MP Andrea Leadsom said.
Many of our MPs have already revealed who they will be backing to become the next Prime Minister.
