A recall petition will be opened in Peterborough on Tuesday 19 March 2019 which could unseat the city's MP Fiona Onasanya.
The 35-year old was jailed after being found guilty of perverting the course of justice.
Despite being kicked out of the Labour Party, she continues to sit in Parliament as an independent.
Voters in her constituency will now have six weeks to sign a petition. If it attracts the signatures of 10 per cent of the electorate then she'll be forced out and a by-election called.
