Home secretary plans to proscribe group that broke into Brize Norton, effectively branding it a terrorist organisation

The pro-Palestine group that broke into RAF Brize Norton sparking a major security review is expected to be banned by the government next week in a move which will anger campaigners.

Yvette Cooper, the home secretary, is planning to proscribe Palestine Action, effectively branding it a terrorist organisation.

She is preparing a written ministerial statement that will be placed before parliament on Monday, a Whitehall source confirmed. It will then need to be enacted through new legislation. If passed, it will make becoming a member of the group illegal.

The decision comes as a security review begins at military bases across the UK, after activists broke into the RAF base in Oxfordshire and sprayed two military planes with red paint.
