Greenpeace activists fit the statue of Churchill at Parliament Square with an emergency face mask to demand action on air pollution.
A separate Greenpeace team eluded security and climbed over the fence around the Houses of Parliament to put another mask on Oliver Cromwell’s statue. Famous statues of Queen Victoria opposite Buckingham Palace, Eros at Piccadilly Circus and Nelson’s Column at Trafalgar Square, have also been given protection against London’s dirty air by environmental activists.
