A political officer in the GMB union is in hot water after retweeting an anti-semitic conspiracy theorist, whose tweet suggested that Jewish influence was behind attempts to undermine Jeremy Corbyn’s leadership of the Labour Party.

Neil Smith retweeted a picture of Peter Mandelson on holiday with Jacob Rothschild, with text claiming the Rothschild family own 80% of Israel and asking ‘do Blairites weaponise antisemitism against Corbyn supporters?’

The tweet was originally posted by @vanremny, whose previous tweets include allegations that Jews were behind the 9/11 attacks.

We understand that a complaint has been made to union bosses. Smith has now taken down the tweet, following the complaint.
