Northamptonshire South MP Andrea Leadsom has won the backing of former London mayor Boris Johnson in her bid to become the new leader of the Conservative Party and Prime Minister.
The Energy Minister launched her campaign on Monday and has the support of around 40 of her fellow Tory MPs.
The first round of voting is taking place with a result expected by 7pm on Tuesday. There are five candidates standing - Theresa May, Michael Gove, Stephen Crabb and Liam Fox as well as Andrea Leadsom - and the one with the least votes will be eliminated.
Boris Johnson was expected to join the race but he dropped out after Michael Gove decided to stand. Theresa Mayis currently the front-runner with the backing of 120 MPs including 24 from the Anglia region.
Further rounds of voting will reduce the number of candidates to two with the winner then elected by the Conservative Party membership over the summer.
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.
