Suspended Labour MP Zarah Sultana has announced she is starting a new party with former Labour leader Jeremy Corbyn.
Sultana, stripped of the Labour whip last year for backing a move to scrap the two-child benefit cap, said she was also resigning from the party after 14 years of membership.
The MP for Coventry South said the new party would be formed with other independent MPs, campaigners and activists, aiming to challenge a "broken" Westminster system.
Corbyn has been contacted but has not confirmed his involvement to the BBC.
However last night, he had hinted he may form a new party, telling ITV's Peston "there is a thirst for an alternative" and that a "grouping will come together".
In a social media post, Sultana said the government is "an active participant in genocide" in Gaza - and highlighted growing poverty, the government's position on welfare, and the cost of living as reasons for establishing her new party.
"Labour has completely failed to improve people's lives. And across the political establishment, from Farage to Starmer, they smear people of conscience trying to stop a genocide in Gaza as terrorists.
"But the truth is clear: this government is an active participant in genocide. And the British people oppose it."
Israel has strenuously denied accusations it is committing genocide or genocidal acts in Gaza.
Sultana added: "The government wants to make disabled people suffer; they just can't decide how much".
"We're not an island of strangers," she says, referencing a speech given by the prime minister in May about immigration, which he has since said he regrets. And she says at the next election, "the choice will be stark: socialism or barbarism".
The Labour Party has been approached for comment.
