A short service for around 100 people, led by the Dean of Westminster, will be held to receive Baroness Thatcher's body into the Chapel of St Mary Undercroft in the Palace of Westminster at 4pm on Tuesday, Downing Street said today.
The chapel will be open from 5pm to 9pm on Tuesday so that MPs, peers and parliamentary staff can pay their respects.
Carol Thatcher has thanked those who has sent her messages of support after the death of her mother Lady Thatcher.
In a statement outside her mother's former home in Belgravia she said: "this is going to be a tough, tearful week, even for the daughter of the Iron Lady."
Tory MPs have joined a campaign to get an obscure punk record about Baroness Thatcher to rival 'Ding Dong The Witch is Dead' at the top of the music charts.
Former MP Louise Mensch urged Thatcher supporters to buy the 1979 track 'I'm in Love with Margaret Thatcher' by the Notsensibles, using the 'Grantham Style' hashtag:
Never thought I'd enjoy punk rock so much #GranthamStyle
Mark Biddiss, who started a social media campaign to get Ding Dong The Witch Is Dead to number one in the charts, said buying the song was "a very cathartic experience for a lot of people who feel that for many years they haven't been listened to".
He was joined on ITV's Daybreak by former Conservative MP Jonathan Aitken who said the song, which is on course for a place in the top five in Sunday's Offical Chart, was a "pretty feeble form of protest".
Anti-Thatcher protestor Chris Kinght has told Daybreak that Saturday's Margaret Thatcher death 'party' on Saturday will be as "distasteful" as it can be.
He said: "We're going to be celebrating the death of this blood sucking vampire."
FW de Klerk, the last president of apartheid South Africa, will be attending the funeral of Baroness Thatcher, as a guest of the Thatcher family, a spokesman for the FW de Klerk foundation has said.
Mr de Klerk, who ordered the release of Mandela and agreed to negotiations that ended apartheid, earlier paid tribute to Lady Thatcher "not only as one of Britain's greatest Prime Ministers but also as a leader whose policies and approach had a significant impact on politics throughout the world".
"From my first meeting with her in London after my election as leader of the National Party in 1989 and throughout the rest of her tenure as Prime Minister, she gave strong and valued...
"Support to me and to all other leaders who were working for a peaceful, prosperous, and constitutional future for South Africa," he said in a statement.
"We met in the Cape and in London many times after her retirement from office - and before her stroke in 2002. I am honoured to have had Margaret Thatcher as a friend."
Those invited to Thatcher's funeral next Wednesday will have to adhere to a strict dress code, outlined below:
- Full day ceremonial without swords
- Morning dress (black waistcoat and black tie) or dark suit
- Day dress with hat
- Medals and decorations may be worn
Deputy Prime Minister Nick Clegg has said it would be a "bit odd" to hold "the knockabout" of Prime Minister's Questions on the same day as Margaret Thatcher's funeral.
The service at St Paul's Cathedral next Wednesday clashes with Parliament's scheduled weekly cross-examination of David Cameron.
A motion tabled last night to delay the start of Commons proceedings until 2.30pm on the day, effectively cancelling PMQs, is expected to be passed when MPs return to Westminster from their Easter break on Monday.
Speaking during his weekly radio phone-in on LBC 97.3, Mr Clegg said he expected Mr Cameron would hold discussions with Commons Speaker John Bercow about the arrangements in the House on the day.
