Members of Momentum - the pro-Corbyn campaign group within Labour - are more likely than other Labour members to think alleged antisemitism in the party was "wildly exaggerated" by the party's opponents.

A total of 73 per cent of Labour members agreed with the statement that Jew-hate in the party was "wildly exaggerated by right-wing media and opponents of Jeremy Corbyn", a poll by Lord Ashcroft found.

But the figure rose 92 per cent among Momentum members, just six per cent of whom felt antisemitism "was a real issue" in the party.

Overall, 22 per cent of Labour members agreed that antisemitism "was a real issue", while 45 per cent agreed antisemitism was "wildely exaggerated" but felt "the party leadership should have done a better job of handling it".

The Community and Security Trust's Dave Rich, an expert in left-wing Jew-hate, shared the poll, saying it was "not hard to spot where Labour's biggest problem of antisemitism denial is coming from".

The poll also showed those who had backed Mr Corbyn in both leadership elections he fought were far likelier to blame the media and political opponents for the antisemitism issue.

A total of 39 per cent who backed Mr Corbyn agreed that the Jew-hate issue was entirely the fault of the right-wing media and his opponents, compared with five per cent who backed Owen Smith in 2016 and just four per cent who backed Liz Kendall in 2015.
