Even without a by-election, the Corbynites could soon purge the Labour party
From our UK edition
The fallout from Frank Field's decision to resign the Labour whip over the leadership's handling of anti-Semitism allegations continued today. Field wants to stay on as a Labour party member but act as an independent in Parliament. The Labour leadership doesn't look kindly on this arrangement and has given him two weeks to withdraw his resignation – or face expulsion. Field has no plans to play ball. However, the issue that has the Corbynistas most excited is the prospect of a by-election. Field is under no obligation to go to the polls but on a blitz of the broadcast studios this morning, he said he is considering it.
