Stop Arming Israel, that is one of the campaigns by Jews for Justice for Palestinians.
They are also trying to block the Jewish community from changing the universal jurisdiction law which currently allows Israeli politicians and military officials to be arrested.
They have boycott, divestment and sanctions campaigns against Israel.
It appears that Liberal Judaism is giving them a platform by allowing them to use their Montagu Centre for one of their meetings.
Should this be happening at the Montagu Centre? Does the Liberal Jewish community agree on this?
