An MP of Palestinian descent has blasted people who use antisemitism while attacking Israel, telling BBC Question Time's audience: "It does nothing for the Palestinian cause."

Lib Dem Layla Moran was on debate programme's panel on Thursday when an audience member asked whether Jeremy Corbyn's failure to tackle Jew-hate in Labour made him unfit to be prime minister.

"The buck stops with him. He's the leader," Ms Moran said. "The bit that really makes me sad about this... There's another side of this and it's a slightly more insidious, frankly slightly gentler antisemitism... which is about using the wrong language."

She added "a lot if it is to do with Israel".

Ms Moran, whose mother was born in Jerusalem, raised the example of the posters that were put up around London, after Labour belatedly adopted the International Holocaust Remembrance Alliance (IHRA) definition of antisemitism, that said "Israel is a racist endeavour".

This was intended to mock the definition, which cites these words as an example of potential Jew-hate.

Ms Moran said: "When you see posters go up, it takes so long for the top of the party to be able to say 'no, that is antisemitic'."

She added she "essentially had to explain" to John McDonnell why they were antisemitic when they both appeared on the BBC last September.

Ms Moran was applauded as she told the Question Time audience: "It does nothing for the Palestinian cause. My plea to those who feel they need to step up for the Palestinians: Please do that, my God do we need it but also please don't do it in a way that stokes antisemitism.

"You can do both. You don't have to be pro-Palestinian and antisemitic."
