Nigel Farage has reignited calls for a ban on cousin marriage after demanding a conversation on the "inherently un-British" practice.
The Reform UK leader, who previously called for a conversation on a burka ban, set out his stall in response to Sweden's decision to ban cousin marriage earlier today.
He said: "It causes serious health problems in certain communities, and it's inherently un-British.
"We must have a serious conversation about a ban in Britain, too."
Tory MP Richard Holden attempted to force a vote on banning cousin marriage last year.
However, Mr Holden was unable to secure time to debate his proposed Private Members' Bill, with the legislative process officially ending after the King's Speech on May 8.
The Shadow Transport Secretary appeared critical of Mr Farage's intervention, labelling the Reform UK leader's response as "weak".
"If he spent more time in Parliament, he’d see we’re beyond ‘conversations’," Mr Holden said.

"Nigel should catch up with Kemi Badenoch & Conservatives who’ve already tabled laws and amendments to ban first cousin marriage."
Speaking to GB News earlier this year, Mr Holden accused Labour of secretly backing cousin marriage by refusing to support his push to ban the practice.
He told The People's Channel: “If you don’t back first-cousin marriage, you can just say so.
"But Labour do back first cousin marriage and they’re trying to hide their secretive support for the practice.
"It is an issue bound up with serious health implications, closed communities, and the isolation of the vulnerable.
