A patron of a charity that organised for two Labour MPs to visit the West Bank shared an anti-Semitic video by a former Ku Klux Klan leader.

Abtisam Mohamed and Yuan Yang, Labour MPs for Sheffield Central and Earley and Woodley respectively, were turned away at Israel’s border on Saturday because they had travelled to the country to spread “anti-Israel hatred”, the country’s authorities said.

They were part of a parliamentary delegation to the West Bank that had been organised by Medical Aid for Palestinians (Map) and the Council for Arab-British Understanding (Caabu).

It can now be revealed Dr Swee Chai Ang, a founding trustee and honorary patron of Map, shared a video by David Duke, the former KKK grand wizard, titled “CNN Goldman Sachs & the Zio Matrix” in 2014.

The video features an extended rant by Duke in which he claimed “the Zionist matrix of power controls media, politics and banking” and that “some of the Jewish elite practices racism and tribalism to advance their supremacist agenda”.

Sending the video to her contacts via email, Dr Ang wrote: “This is a shocking video please watch. This is not about Palestine – it is about all of us!”
