A demonstration in Parliament Square by two Jewish groups has drawn attention to Jeremy Corbyn’s anti-Semitism problem. Many leading British Jews have written to him complaining that Labour contains pockets of anti-Semitism that he has turned a blind eye to or dealt with inadequately. Jewish Labour MPs have been subjected to anti-Semitic rants and intimidation from supporters of the hard left. Jewish students have abandoned Labour groups, feeling threatened and vilified. The hard left is almost defined by its hostility to Israel, and in the heat of political debate ancient hatreds flame. Labour candidate Alan Bull said the Holocaust was a ‘hoax’. Corbyn called Hamas and Hezbollah ‘friends’. He is a Facebook member of Palestine Live and History of Palestine, riddled with anti-Semitism under the cloak of pro-Palestine activism. See
