Nadine Dorries quits as MP with immediate effect and triggers by-election
Conservative MP Nadine Dorries has resigned her seat with immediate effect triggering a by-election contest to decide who will replace her.
The former culture secretary, 66, said it was time for someone younger to represent the seat.
She had already announced she would not be contesting the next general election.
I have today informed the chief whip that I am standing down as the MP for Mid Bedfordshire, with immediate effect, she said in a statement posted on Twitter.
It has been an honour to serve as the MP for such a wonderful constituency but it is now time for someone younger to take the reins.
