"God, lift the curse of the Jews off the Muslims in Palestine."
The remarks were met with enthusiasm and approval from demonstrators draped in Palestinian flags in the crowd.
In a post on her Twitter page, the Shadow Minister for Community Cohesion explained that she does not speak Arabic and wasn’t aware at the time of the antisemitic remarks being made.
Ms Shah said: “Over recent weeks, a small minority of individuals have been trying infiltrate demonstrations about the situation in Palestine to spew hatred.
“I was made aware that an individual present at one of the rallies I spoke at, made remarks following the rally in Arabic – a language I do not speak. The individual was not a speaker but gained access to a microphone – the translation of their comments given to me are not remarks I’d ever make.
“I will never shy away from using my voice to raise the plight of the Palestinian people, but I will never tolerate antisemitism and I totally condemn anyone perpetrating it.”
