Jonathan Aitken, former Conservative Minister, told ITV's Daybreak that Margaret Thatcher was "quite lonely" in her final years but said one of the last dinner parties he invited her to was a "wonderful evening of reminiscences".
Margaret Kittle, 79, said she travelled from Canada for the funeral as soon as she heard of Lady Thatcher's death, taking up her position outside St Paul's Cathedral at 8am yesterday.
John Loughrey, 58, arrived at St Paul's shortly after Mrs Kittle yesterday morning.
Baroness Thatcher's ceremonial funeral is a "fitting tribute" to a major national figure, David Cameron said.
Mr Cameron told BBC Radio 4's Today programme: "I think it will be quite a sombre event but it is a fitting tribute to a great prime minister, respected around the world.
"I think other countries in the world would think Britain had got it completely wrong if we didn't mark this in a proper way."
The Prime Minister urged the Iron Lady's political opponents to show "respect" during the event, even though they may have disagreed with her policies.
Labour peer, Baroness Helena Kennedy told Daybreak that she found the military element to Margaret Thatcher's funeral "unattractive", she said she would have preferred a much smaller affair.
"This kind of public ritual is in some ways replacing other things that have been lost and in some ways I think that is what this is about", she added.

Former Met police commander Bob Milton told Daybreak that it would be highly unlikely someone would attempt a terrorist attack on Margaret Thatcher's funeral today.
More than four thousand police officers have been drafted in for the funeral, amid fears of demonstrations and protests.
