Winston Churchill in 1965. Other world leaders, including . Canada's Stephen Harper, Mario Monti of Italy and Polish Prime Minister . Donald Tusk, are attending the service in person. A key Reagan-era ally of Baroness Thatcher, former U.S. Secretary of State George Shultz, will attend . President Obama paid tribute to Lady Thatcher's towering achievements when her death was announced last week. But a US embassy spokesman confirmed . that no serving member of his administration would be present to pay . their last respects, citing a busy week in US domestic politics. Former US vice president Dick Cheney and ex-secretary of . state Henry Kissinger will attend the funeral, Downing . Street said today. Former defence secretary Dr Liam Fox, . Lady Thatcher's closest ally in modern-day politics, said: 'I think it . would be both surprising and disappointing if after President Obama's . fulsome tribute to Lady Thatcher, the American administration did not . send a senior serving member to represent them.' Sir Gerald Howarth, chairman of the . Thatcherite Conservative Way Forward group of MPs and peers, said: 'The . bonds forged between the UK and the US through Ronald Reagan and . Margaret Thatcher was instrumental in ending the Cold War and liberating . millions of people. 'That the present administration feels . unable to be represented as the world marks the extraordinary . contribution Margaret Thatcher made will be a source of disappointment . to those who served with her in that great endeavour.' The US embassy insisted no snub was intended, but confirmed that Mr Baker and Mr Schulz would represent the US. 'This is a hugely significant week in terms of US domestic politics,' a spokesman added. He said that both the First Lady and . the Vice President were 'the President's point people on gun control', . adding: 'This is a week when there is a lot of movement on Capitol Hill . on gun control issues.' Last night police in London were under pressure to crack down on plans to insult the memory of Lady Thatcher at the funeral. Hundreds of protesters have pledged to turn their backs as her coffin travels through Central London. Campaigners said Scotland Yard had . effectively encouraged the move by decreeing it is not against the law . and will not provoke arrests. The insult is calculated to cause maximum embarrassment to her grieving family without provoking action by police. It will be seen by millions worldwide as the occasion is beamed live around the world on TV.

Hundreds have signed up to online sites vowing to wear red and turn their back on the military funeral cortege. They want to occupy high- profile points of Lady Thatcher's three-mile funeral procession so their views will not be missed. John Cooper QC, the architect behind . the back-turning protest, said the public nature of the funeral means it . is impossible to ban insulting gestures. He said: 'Simply saying it is beastly, . horrible or distasteful – a point of view that I can understand – does . not take away the fact there will be a proportion of society that . rightly wants to legally demonstrate.' Retired chief constable Dr Tim Brain . said police are forced to tread the line between the right to protest . and upholding the law.

In a full and detailed rehearsal, each . man, woman and horse involved in the last stage of the procession . enacted the role they will play tomorrow. It created the bizarre but often . stirring spectacle of military marching bands playing to no one, . bearskin guardsmen with no crowds to flank – even a minister saying a . prayer over an empty coffin. This was the last chance any of them . had to practise for the real thing – the largest funeral in Britain . since that of the Queen Mother in 2002.

In the interests of military . precision, a final calculation confirmed that the procession would have . to walk at 70 steps a minute over a journey of some 1,200 yards, as well . as allowing time for choreographed pauses. It was clearly a useful . fine-tuning exercise – the coffin is reported to have arrived three . minutes and 15 seconds over schedule. Major Andrew Chatburn, who has the job . of organising it all, said the rehearsal was vital to allow those . taking part 'to get a feel for how it's going to go so they can perform . their duties with confidence on the day'.
