The Holocaust denying former Grand Mufti of Jerusalem, who has called for Britain to be destroyed, is set to visit Parliament next week.
Sheikh Ekrima Sabri will be in Britain from 11 to 15 September, as guest of pro-Palestine group EuroPal to discuss the "recent escalation" in Israel with MPs.
Sabri has a history of anti-Semitic and terrorist-supporting views, which led to his removal as Jerusalem's Islamic leader by Palestinian President Mahmoud Abbas in 2006.
He threatened that Jewish prayer at Jerusalem's Temple Mount would "prompt massacres" and lead to "rivers of blood". And during interview with Italian newspaper la Repubblica, Sabri flatly denied the Holocaust, stating: "Six million Jews dead? No way, they were much fewer. Let's stop with this fairy tale exploited by Israel to capture international solidarity."
