Today's May Day March in London's Trafalgar Square was held in honour of the recently passed Bob Crow and Tony Benn.

The rally followed a two-day strike that caused severe delays on the Tube network. The strike was called over Transport for London (TfL) plans to close the network's ticket offices.

The mayor of London Boris Johnson was branded a "Tory liar" by Frances O'Grady, the general secretary of the TUC, as the dispute between managers and trade unions over the London Underground continues.

Len McCluskey, the general secretary of Unite, also spoke at the event.
