The following is from a Wikipedia article on MPACUK:
“It has also attracted criticism for its strong anti-Zionist stance, and for publishing antisemitic material. The 2006 British All-Party Parliamentary Report into Antisemitism alleged that the group has used material from Holocaust denial and neo-Nazi publications, uses the word "Zionist" as a replacement for "Jew", and engages in the spread of conspiracy theories about Jews. MPACUK was described by Jack Straw as "most egregious" after it actively campaigned for Muslims in his Blackburn constituency to vote tactically against him in the 2005 general election…
"MPACUK has attracted criticism for alleged antisemitism. In September 2006 the Report of the All-Party Parliamentary Inquiry into Antisemitism observed that MPACUK had been criticised by the CST for promoting the idea of a worldwide Zionist conspiracy and using material taken from neo-Nazi, white nationalist, and Holocaust denial websites. The report also notes the CST's assertion that "[t]he use of ‘Zionist’ as a replacement for ‘Jewish’ is common on the MPACUK website" and that MPACUK has articulated antisemitic conspiracy theories through the language of anti-Zionism…
"MPACUK, with Al-Muhajiroun and Hizb-ut-Tahrir, was the subject of a no-platform order by the National Union of Students in 2004, because of its alleged publication of antisemitic conspiracy theories and inciteful racist material, and further material on its website encouraging activists to break the law.
Lorna Fitzsimons Controversy
"Labour MP Lorna Fitzsimons became the target of an MPACUK campaign when she stood for re-election at the 2005 General Election in the constituency of Rochdale, which has a significant Muslim population. The All-Party Parliamentary Report noted with concern MPACUK's campaign against Lorna Fitzsimons and that leaflets had been printed by MPACUK, which claimed that Fitzsimons had done nothing to help the Palestinians because she was a Jewish member of the Labour Friends of Israel. Fitzsimons, who was a member of the Labour Friends of Israel, is not in fact Jewish. MPACUK later apologised for the inaccurate description. It did not, however, reject the idea that a candidate's Jewish background should be a valid reason for Muslims to vote against them.
"In a 2008 Facebook thread [MPACUK's] Bukhari said: "Muslims who fight against the occupation of their lands are 'Mujahadeen' and are blessed by Allah. And any Muslim who fights and dies against Israel and dies is a martyr and will be granted paradise ... There is no greater oppressor on this earth than the Zionists, who murder little children for sport." He later added: "Any public attack on Islam and the Ummah is not going to be tolerated by men like me. I have dealt with these Zionists before, a veneer of reason, below which lies a crooked mind plotting and planning to extend their hatred against us."
"Bukhari also felt the people of Israel to be "the most blood thirsty and violent people on earth." He asked not to apologise for Jihadists anymore, which he feels is a racist term. The British Centre for Social Cohesion has passed his comments onto the police and called into question the media outlets' use of MPAC UK and their portrayal of it as a mainstream Muslim organization. When asked by Daily Telegraph journalist Damian Thompson for comment, Bukhari confirmed these stances, adding "I stand by that, and I think any Muslim in the world stands by that...""
