Baroness Thatcher's coffin is being moved to a chapel in the Palace of Westminster where it will lie in rest before her funeral tomorrow.
Argentina's ambassador to London has declined an invitation to attend the funeral of Baroness Thatcher.
No 10 invited Alicia Castro to tomorrow's proceedings but did not extend an invitation to President Cristina Fernandez de Kirchner.
The Prime Minister's official spokesman said the decision to refuse was a "matter for the Argentine ambassador".
Former US vice president Dick Cheney and ex-secretary of state Henry Kissinger are to attend the funeral of Baroness Thatcher, Downing Street said.
A senior church figure who will play a central role in Baroness Thatcher's funeral has said Britain has yet to come to terms with the "hurt and anger" felt in some parts of British society as a result of her policies, The Times (£) reported.
The Dean of St Paul's Cathedral, the Very Rev Dr David Ison, reportedly said people should ask themselves why the country's first female Prime Minister was still such a controversial figure 23 years after being forced out of office.
Dr Ison, who will give the bidding at tomorrow's service, made the comments when asked if the funeral of Lady Thatcher was an historic occasion.
"I think it's emblematic of a particular point in British society", he said.
"You have to ask yourself the question why it is 23 years after she left Government, Margaret Thatcher is still such a controversial figure and I think part of the answer is we still haven't come to terms with the hurt and anger many parts of society have felt because of the legacy of her policies".
The dean reportedly made the remarks in an interview with CNN International, which is due to be broadcast today.
MPs will debate later today whether Wednesday's Prime Minister's Questions session should be cancelled so members of the Commons can attend Baroness Thatcher's funeral
George Galloway and Labour veteran Dennis Skinner objected to a motion that would have allowed the chamber's sitting times to be altered.
The pair's cry of "object" means the proposed change will now be voted on after a debate lasting up to three hours.
Mr Galloway described Lady Thatcher as "a wicked and divisive woman" who did "great damage to a society she said didn't exist".
Mr Galloway said, "People think the canonisation of Lady Thatcher has gone on long enough. The muffling of the chimes of Big Ben is a step too far and now Mr Cameron will miss Prime Minister's Questions for four weeks. It is unconscionable".
Conservative MP Peter Bone has told Daybreak that London could profit from Margaret Thatcher's funeral as more people wishing to pay their respects have been brought into the area. He said:
I don't first of all accept that this is costing £10 million, because think how many people have been brought into London, how much extra business, it's probably actually going to work out as a profit for the economy.
It is absolutely the correct thing to do.
Labour MP John Mann told Daybreak that "taxpayers should not be spending money on a politician's funeral". He added:
The question is how respects are paid, of course it's right that respects are paid to people who have died, and if they are national leaders then the nation should duly do so and I think that's quite appropriate.
But spending £10 million plus on a funeral for a divisive politician is wrong in my opinion wrong.
The body of Baroness Thatcher will make its final journey to Parliament ahead of a potentially bitter debate in the Commons about her legacy.
The debate, triggered by outspoken left-winger George Galloway, will take place in the Chamber while the former prime minister's coffin lies nearby in Parliament's Chapel of St Mary Undercroft.
Respect MP Mr Galloway, who claimed he would have "a lot to say" about the "wicked and divisive" Conservative premier, objected to planned changes to the Commons' sitting times tomorrow to allow for Lady Thatcher's ceremonial funeral.
