BARONESS Thatcher will receive a Falklands guard of honour at her funeral, with those bearing her coffin drawn from the ships, squadrons and regiments associated most closely with her greatest triumph at No 10.

Prime Minister David Cameron led the tributes at Westminster, which was recalled in a special session to mark her death, saying she had "made our country great again".

Sir Mark Thatcher, in his first public statement since the death of the former prime minister from a stroke was announced on Monday, said the family had been overwhelmed by the messages of condolence and support they had received.

He said his mother would have been humbled by the presence of the Queen at St Paul's Cathedral next Wednesday.

The streets of central London will be lined by men and women from all three services for the procession to St Paul's.

More than 700 Armed Forces personnel will take part.

Three military bands will play, their drums draped in black, while processional minute guns will be fired from Tower Wharf at Tower Bridge.

The 10 coffin-bearers will be drawn from those units most closely associated with the Falklands War, including the Scots Guards – involved in one of the fiercest battles to take Mount Tumbledown – the Parachute Regiment, the Welsh Guards – who suffered many casualties when the Sir Galahad was bombed by Argentinian jets – the Gurkha Rifles and the Royal Navy, Marines and the RAF.

Downing Street said the coffin will be borne from St Clement Danes Church in The Strand to St Paul's on a gun carriage drawn by six horses. A band of the Royal Marines will take part in the procession.

In the Commons, Mr Cameron told MPs: "They say: Cometh the hour, cometh the man. Well, in 1979 came the hour and came the lady. "She made the political weather, she made history, and – let this be her epitaph – she made our country great again."

Labour leader Ed Miliband said Baroness Thatcher had defined the politics of a generation. He said: "Whatever your view of her, Margaret Thatcher was a unique and towering figure."

Deputy Prime Minister and Liberal Democrat leader Nick Clegg added: "[The fact that] those of us who are not from her party can shun the tenets of Thatcherism and yet still respect Margaret Thatcher is part of what was so remarkable about her."

Among those who attended the Westminster special session, Michael Meacher, the former Labour minister, denigrated Baroness Thatcher's "scorched earth" tactics, which had "polarised" the nation. Too many industries, too many working-class communities across the north were laid waste during those years without any alternative and better future to replace what had been lost," he said.

His Labour colleague Glenda Jackson sparked howls of protest from the Tory benches when she launched a full-frontal assault on the "heinous" Thatcher record.

In the Lords, Michael Howard, the former Tory leader, said: "There are very, very few people who have made a difference on the scale Margaret Thatcher achieved. She saved our country, she helped bring freedom to half our continent. The light of her legacy will shine like a beacon down the generations."

Labour peer Lord Soley said if Conservative policy had been different in Scotland, then the Tories would still be a significant party north of the Border.

Meanwhile, it was confirmed Tony Blair and his wife Cherie will be at the funeral, as will Gordon Brown and his wife Sarah. First Minister Alex Salmond and FW de Klerk, the last president of apartheid South Africa, will also attend.

Nancy Reagan, widow of the late US President Ronald Reagan, who is "heartbroken" by the death, cannot attend.
