At the same time, left-wing protesters are expected to be in Trafalgar Square, the scene of the worst of the poll tax rioting, in a "celebration" of Baroness Thatcher's death from 6pm. The event, billed as "the party of a lifetime", is thought to have been planned by anarchist groups for some years, having been pencilled in for 'the Saturday after Thatcher dies'. It may involve the toppling of a statue and a mock funeral.
