“There is a whole wealth of evidence out there about what the problems are.”

On 31 October 2015, the families and friends of those who have died while in the custody of the state will hold their annual remembrance procession from Trafalgar Square to Downing Street.

They will assemble at 12noon in Trafalgar Square and make their way in silence along Whitehall for a noisy protest at Downing Street.
