Downing Street has released the first list of invitees for the former Prime Minister's funeral service, to be held next Wednesday (April 17).
All surviving British prime ministers and US presidents have received invitations, along with a representative for Ronald Reagan's family, as his widow Nancy is too frail to travel.
The Queen and Prince Philip are confirmed to be attending the service, which will take place at St Paul's Cathedral in London. It will be the monarch's first funeral service for a British politician since Sir Winston Churchill in 1965.
Jeremy Clarkson, Sir Terry Wogan and Lord Andrew Lloyd Webber are among those from the world of showbiz to have received invites.
Joan Collins, Sir Trevor McDonald, Sir Tim Rice, June Whitfield, Sir David Frost, Lord Jeffrey Archer and Michael Portillo are also on the guest list.
Elsewhere, all surviving members of Baroness Thatcher's cabinets are invited, along with Labour leader Ed Miliband, the current cabinet and the First Ministers of Scotland, Wales and Northern Ireland.
Former US Secretary of State Hillary Clinton, European Commission President Jose Manuel Barroso and a representative of Nelson Mandela have also been invited.
Over 2,000 people have been invited overall, with the invites expected to be delivered tomorrow (April 12).
David Dimbleby is to present the BBC's coverage of Margaret Thatcher's funeral, which begins at 9.15am.
Baroness Thatcher died on Monday at the age of 87, after suffering a stroke.
