Скачать или смотреть ‘London Bridge is down’: Enormous security operation for Queen’s funeral in full swing

The death of Queen Elizabeth II has triggered one of the most meticulously rehearsed and planned security operations in UK government history – Operation London Bridge.

For many government and security personnel, this will be the biggest operation of their careers.

The plan spans many organisations, including UK government departments, the Church of England, the Metropolitan Police Service, the British Armed Forces, the media, the Royal Parks, London boroughs, the Greater London Authority and Transport for London.

Former chief superintendent Owen West called it “the largest and most complex policing mobilisation in living memory in the UK”.

Around a million people are expected to visit the late monarch as she lies in state at Westminster Hall for four days ahead of her funeral on Monday, 19 September.
