UPDATE: London Mayor Sadiq Khan and Newham Mayor Rokhsana Fiaz have both declared their opposition to the “abhorrent” DSEI arms fair, which sees weapons sold to oppressive regimes, being held in the London Borough of Newham. Policing costs now reach £1m.

Eyewitness video of Lin Patterson being arrested at the DSEI arms fair filmed by Bath Quaker Ali Morgan. “It was quite shocking,” Ali said, “the huge mob of police sent to protect the arms supplies from a fairly small non- violent protest. And despite the fact that they knew that the Quaker meeting would end at 1500 a police spokesman barged into the middle of the silent meeting at 1430 to announce to everyone that they risked arrest if they didn’t move at 1500.
