Baroness Thatcher had discussed plans for the ceremony before her death and will not lie in state at her own request.

Where is the funeral?
The service will be held at London's St Paul's Cathedral. A funeral procession will travel from the Palace of Westminster to the cathedral just under two miles away, with members of the armed services lining the route.
The day before the funeral the coffin will be transferred to the Chapel of St Mary Undercroft in the Palace of Westminster. There will be a short service following its arrival before the coffin rests in the chapel overnight.
The service at St Paul's will be followed by a private cremation.
The St Paul's ceremony is not open to the public but will be televised. Members of the public are able to line the route.
What is the procession route?
Dozens of streets in Central London will be closed in the hours running up to the ceremony

Thatcher’s coffin will be taken by a hearse to the RAF Chapel, the church of St Clement Danes, in the Strand.
From there her coffin will be transferred to a gun carriage drawn by the King’s Troop Royal Artillery.
The impressive cortege will then proceed down the Strand, through Aldwych, then along the entire length of Fleet Street before rising up Ludgate Hill to the majestic St Paul’s Cathedral, which was chosen at her request.
What are the military honours?
Military personnel from the RAF, Navy and Army will line the route from Westminster to St Paul's. The coffin will travel part of the way by hearse before being transferred to a gun carriage at the Church of St Clement Danes, the RAF Chapel, on the Strand. The gun carriage will be drawn by the King's Troop Royal Artillery.
