How long has it been since Nadine Dorries said she would quit? Follow with our live counter
Nadine Dorries has formally quit the House of Commons, some 78 days after vowing to do so "with immediate effect".
On Tuesday she was appointed to the post of Steward and Bailiff of the Three Hundreds of Chiltern - the archaic mechanism by which MPs can quit the Commons.
She had faced moves to remove her from her seat when Parliament returned in September, after the Lib Dems announced plans to table what the party is calling the "Dosser Dorries Bill".
The bill proposed a 10-day suspension if she did not appear on 4 September, possibly triggering a by-election if it won the support of MPs.
It was the latest attempt to dislodge the Mid Bedfordshire MP, coming hot on the heels of other opposition politicians, campaigners and constituents.
Since announcing her resignation on 9 June, Ms Dorries had spoken publicly on TV only a handful of times, had not held a single constituency event, and refused to officially quit.
In the days following her decision - made publicly on Twitter - the Tory former cabinet minister delayed her resignation to investigate why she was not given a peerage, amid speculation that Prime Minister Rishi Sunak had intervened to block the award.
Since then, she has appeared on her Talk TV show several times, tweeted her columns for the Daily Mail, and helped hedgehogs back to health.
But pressure had steadily mounted for her to formally resign, triggering a long-awaited by-election.
ITV News Anglia looks at a timeline of events since Ms Dorries said she would stand down.
