Briefing paper warned proscription could also heighten Muslim-Jewish tensions and be seen as favouring Israel

Ministers banned Palestine Action despite being told by their advisers it could “inadvertently enhance” the group’s profile, an official government document shows.

The briefing paper was written three months before the proscription of the group, which was set up to take direct action to halt UK arms supplies to Israel.

It was prepared in March by officials at the Home Office and the Ministry of Housing, Communities and Local Government, helped by experts in counter-terrorism policing.

Its contents were obtained by the investigative website the Detail and shared with the Guardian.
