A service will be held on Tuesday afternoon before Lady Thatcher's funeral in the Chapel of St Mary Undercroft in the Palace of Westminster, where her body will rest overnight.
The short service, for around 100 people, will be led by the Dean of Westminster and attended by members of the family, senior figures from both Houses of Parliament and staff from Parliament and Downing Street who knew or worked closely with the former prime minister.
After the service, the chapel will be open for several hours in order that members of both Houses and parliamentary staff may pay their respects. The Speaker's Chaplain will keep vigil in the chapel through the night.
More than 700 armed forces personnel will line the route of the funeral procession from Westminster to St Paul's, including three bands whose drums will be covered in black cloth.
A gun salute will be fired from the Tower of London and the coffin will be carried into St Paul's by service personnel from regiments and ships closely associated with the Falklands campaign.
Following the funeral, the City of London Corporation will hold a reception at London's Guildhall for invited guests.
