The Independent Group for Change has shut down after losing all its MPs in the General Election .
The group, initially known as The Independent Group (TIG), then briefly as Change UK, was founded by MPs who defected from Labour and the Conservatives.
MPs including Chuka Umunna, Sarah Wollaston, Phillip Lee, Luciana Berger, Angela Smith and Heidi Allen, joined the group before later defecting to the Lib Dems.
It was left with leader Anna Soubry, Mike Gapes, Chris Leslie, Joan Ryan and Ann Coffey.
The group tweeted: "We came together & took a stand when others wouldn't.
"It was right to shine a spotlight on Britain's broken politics.
"But having taken stock and with no voice now in Parliament, we begin the process of winding up our party. Thanks to all who stood with us."
In a letter to its members, the party's leader, ex-Tory Anna Soubry, said: "Whilst there is clearly a need for massive change in British politics, now that we no longer have voices within Parliament, a longer term realignment will have to take place in a different way."
She added: "Honesty and realism are at the core of our values, and we therefore must recognise that the political uncertainty of recent months has now given way to a settled pattern in Parliament for the next five years.
"So this is the right time for us to take stock."
