Margaret Thatcher's funeral service has finished at St Paul's Cathedral after a procession through the streets of London.
The Bishop of London, the Right Reverend Richard Chartres, addressed a congregation including politicians, celebrities and foreign leaders.
Earlier there was applause, cheers and a few boos as the coffin passed the crowds lined up by the roadside.
Draped in the Union Flag, the coffin was transferred inside a gun carriage drawn by the King's Troop Royal Horse Artillery.
At the same time, a gun was fired every minute from the Tower of London.
At 10.45am, The Queen arrived, dressed in black, and was greeted by the Lord Mayor of London.
The order of service includes readings from David Cameron and Amanda Thatcher, the former Prime Minister's daughter, and music from Elgar and Vaughan Williams.
Royalty, world leaders and celebrities rubbed shoulders at St Paul's, including former Prime Ministers Tony Blair and John Major, ex US Secretary of State Henry Kissinger and broadcaster Terry Wogan.
Other figures synonymous with the Thatcher years included Falklands veteran Simon Weston, and the Iron Lady's former Chancellor Sir Geoffrey Howe, thought to have been a key figure in her downfall.

The carriage was drawn by six black horses - led by one called Mister Twister - down The Strand, Temple Bar, Fleet Street and Ludgate Hill to St Paul's.
The wheels of the 1.5-ton carriage were changed from steel to rubber so it ran more quietly on the road.
