Margaret Thatcher's Funeral Begins

Being held in St. Paul's Cathedral


Baroness Thatcher's funeral service has begun at St Paul's Cathedral, attended by the Queen and dignitaries from the UK and around the world.

Her union jack-draped coffin was borne to the cathedral on a gun carriage, with a military guard of honour.

Prime Minister David Cameron has called the funeral a "fitting tribute to a great prime minister".

Four thousand police officers are on duty in central London, with large crowds along the route.
