A senior Tory MP will find out later today if she is to be ousted from her seat by her local party members.
Anne McIntosh is facing a bid to be deselected as the Conservative candidate for next year's election in her Thirsk and Malton seat, in North Yorkshire.
Miss McIntosh, 59, has been a prominent figure during the recent flooding crisis as chair of the Commons Environment, Food and Rural Affairs Select Committee.
She has fallen out with her local party's executive, in particular chairman Peter Steveney.
A secret report found that senior Tories in the constituency have fought a long battle with Miss McIntosh to deselect her as the party's candidate in the next election.
Yesterday, Miss McIntosh received the support of Speaker John Bercow and Commons Leader Andrew Lansley.
As Tory MPs cheered their support for the MP, Mr Bercow then added: "I hope the cheers for that proposition will be noted in the north of England."
The internal inquiry found that the local executive broke the rules by co-opting a large number of new members on to the association's executive board weeks before a vote where it was decided not to reselect her for the 2015 general election.
The investigation decided the way she was deselected was "fundamentally flawed" and its result should be set aside.
The Thirsk and Malton seat was created for the 2010 election, when Miss McIntosh won with a majority of 11,281 over the Lib Dems.
She was MP for the now-defunct Vale of York seat from 1997 to 2010.
Local party members are understood to be travelling to London for the ballot count this afternoon.
