The Conservatives have chosen businesswoman Christine Emmett to contest the forthcoming Corby by-election.
The town's MP Louise Mensch is standing down and moving to America where her husband lives. She won the seat from Labour in 2010 with a majority of just under 2000.
Mrs Emmett lives at Morcott in Rutland where her husband runs a holiday homes business.
The former buyer for Marks and Spencer has also been a non-executive director of the Peterborough NHS Trust.
The by-election follows the resignation of former Tory MP Louise Mensch who stood down in August citing family reasons.
Labour leader Ed Miliband has been campaigning in Corby ahead of the crucial by-election there.
There are fourteen candidates standing in the Corby by-election on 15 November following the resignation of Conservative MP Louise Mensch.
