The eight pall-bearers who carried the casket into the Cathedral were drawn from Army units, Royal Navy ships and RAF stations with links to the Falklands war, commanded by Major Nick Mott of the Welsh Guards who served in the 1982 conflict.
Lady Thatcher's grandchildren Michael and Amanda walked ahead of the coffin as it entered the cathedral, carrying cushions bearing the insignia of the Order of the Garter and Order of Merit, which were laid on the altar.
Conservative MPs Conor Burns and Andrew Percy were among those who took part in a service for Lady Thatcher inside a chapel in Parliament ahead of tomorrow's funeral:
Very short, dignified, moving service to welcome Lady T's remains to the Crypt Chapel in the House of Commons. Very intimate

Tube drivers are to vote on industrial action in a row about working conditions.
The announcement has come as Conservatives on the London Assembly called for curbs on strikes on the Underground.
The union organising the ballot called that an attack on fundamental rights.
Rags Martel reports.
Mick Cash, from the RMT Union, says that he does not believe that Londoners want fundamental freedoms - such as the right to strike - to be eroded.
The RMT union said that it was holding a strike ballot "in response to London Underground riding roughshod over agreements and abusing a range of agreed policies and procedures".
They are unhappy with plans to split a depot in Acton Town into two - claiming that that tube bosses are "ripping up rosters and booking times" and "refusing perfectly reasonable requests for decent staff facilities".
RMT General Secretary Bob Crow said:
"Driver and instructor members on the Piccadilly Line are furious at this unilateral attack by the company on working conditions, agreements and procedures and we are moving forwards with plans for a ballot for strike action.
"We will of course be in talks with our sister drivers union ASLEF and London Underground should be in no doubt about the unions determination to protect working conditions and to stop the abuse of procedures."
RMT General secretary Bob Crow said: "One of the first things fascist dictators like Hitler, Mussolini and Pinochet did when they seized power was to ban transport workers from taking strike action so the Tory group on the London Assembly find themselves in some high profile company on this one.
"This crowd have obviously over-dosed on their post-Thatcher adulation and are looking to ramp up the anti-union rhetoric in advance of the publicly financed funeral on Wednesday.
"Of course, banning the fundamental human right to withdraw your labour, a right that distinguishes a free workforce from forced labour, is all the rage on the far right and anyone stupid enough to try and embark on such a policy is doomed to failure."
