Greenpeace activists fit The Victoria Memorial in front of Buckingham Palace 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 Winston Churchill in Parliament Square, Nelson’s Column above Trafalgar Square and Eros at Piccadilly Circus, have also been given protection against London’s dirty air by environmental activists.
