Margaret Thatcher is Britain's most divisive Prime Minister but she will be honoured with a ceremonial funeral with full military honours.
She had discussed plans for her official send-off before her death and will not lie in state at her own request.
Instead of a state funeral, which would require a vote in parliament, Lady Thatcher's funeral will be a ceremonial service with full military honours - similar to the funerals for Princess Diana in 1997 and the Queen Mother in 2002.
What date is the funeral?
The ceremony will take place on Wednesday 17 April. Keep up to date with the latest details on our dedicated page and join our Facebook page to follow the debate.
Where is the funeral?
The service will be held at London's St Paul's Cathedral. The cathedral can hold 2,300 people and is expected to be full. A funeral procession will travel from the Palace of Westminster to the cathedral just under two miles away, with members of the armed services lining the route.
The day before the funeral the coffin will be transferred to the Chapel of St Mary Undercroft in the Palace of Westminster. There will be a short service following its arrival before the coffin rests in the chapel overnight.
The service at St Paul's will be followed by a private cremation.
The St Paul's ceremony is not open to the public but will be televised. Members of the public are able to line the route.
What time will it start?
The service is due to start at 11am. BBC1's coverage is listed as 9.15am to 12.15pm - and we will bring you live coverage online.
What are the military honours?
Military personnel from the RAF, Navy and Army will line the route from Westminster to St Paul's. The coffin will travel part of the way by hearse before being transferred to a gun carriage at the Church of St Clement Danes, the RAF Chapel, on the Strand. The gun carriage will be drawn by the King's Troop Royal Horse Artillery. Six horses will draw the carriage, three of them mounted, with a sergeant riding alongside, an officer riding in front and three dismounted troops on foot.
A Bearer Party made up of all three services will walk alongside the coffin, and will include those from ships, units and stations notable for their service during the Falklands Campaign. Members will be taken from the Royal Navy/Royal Marines; the Scots Guards; the Welsh Guards; the Royal Artillery; the Royal Engineers; the Parachute Regiment; the Royal Gurkha Rifles; and the RAF.
Three military bands will play - their drums draped in black as a mark of respect.
A guard of Chelsea Pensioners, dressed in their traditional red tunics, will line the steps of St Paul’s as her coffin is carried in by bearers from units particularly associated with the Falklands War.
More than 700 Armed Forces personnel drawn from all three services will take part. Members of the Welsh Guards, the regiment that suffered some of the heaviest losses during the Falklands conflict, will be among the units involved, taking on roles including the coffin bearer party, lining the route the procession will take, and forming a Guard of Honour outside St Paul's.
Guns will be fired from the Tower of London but there will be no flypast - as Lady Thatcher herself requested.
How much is it going to cost?
The funeral is expected to cost up to ?10million with the taxpayer bearing the brunt of the costs. It has been confirmed a "contribution" to the cost of the funeral will be made from Lady Thatcher's estate. The official cost to the public purse will be released after the service has taken place.
The security operation alone is set to cost ?5million. Police across the capital have been ordered to cancel any leave they had planned for Operation True Blue next ?Wednesday.
There could be more than 4,000 officers and 2,000 troops lining the route. Hundreds of specialist police will be working on counter-terrorism measures, with others carefully monitoring CCTV cameras for trouble spots.
Every corner of the route will be checked by sniffer dogs, with sewers and drains closed.
Should Margaret Thatcher have a ceremonial funeral?
8000+ VOTES SO FAR
What is the procession route?
Dozens of streets in Central London will be closed in the hours running up to the ceremony
The funeral will begin at Westminster at the Chapel of St Mary Undercroft – known as The Crypt.
Thatcher’s coffin will be taken by a hearse to the RAF Chapel, the church of St Clement Danes, in the Strand.
From there her coffin will be transferred to a gun carriage drawn by the King’s Troop Royal Artillery.
The impressive cortege will then proceed down the Strand, through Aldwych, then along the entire length of Fleet Street before rising up Ludgate Hill to the majestic St Paul’s Cathedral, which was chosen at her request.
Who will be there?
Her children Carol and Mark will lead the mourners. The Queen will attend, accompanied by Prince Philip. It is the first time the Queen has attended the funeral of one of her former Prime Ministers since Sir Winston Churchill's state funeral in 1965.
Hundreds of foreign dignitaries and top UK politicians will be invited. Former PMs Tony Blair and Gordon Brown and their wives Cherie and Sarah have confirmed they will be attending.
Former Soviet leader Mikhail Gorbachev is not attending due to health problems. Ex-US first lady Nancy Reagan, whose husband Ronald worked closely with Thatcher as the Cold War drew to an end, said she was "heartbroken" over Lady Thatcher' death but could not attend due to her age.
FW de Klerk, the last president of apartheid South Africa, will also be there as a guest of the family. Lord Jeffrey Archer and wife Mary, singer Dame Shirley Bassey and composer Lord Lloyd-Webber are also due to attend the service.????
However, Neil Kinnock, the Labour leader defeated by Thatcher at the 1987 election, has said he will not be attending.
Ten members of staff from the Ritz hotel, where Lady Thatcher died on Monday, have also been invited to her funeral as thanks for the care she received. The 87-year-old had been staying at the five-star hotel since Christmas.
What's the dress code?
Guests at the funeral will be asked to wear full day ceremonial dress without swords, morning dress with a black waistcoat and black tie or dark suit, day dress with hat. Medals and decorations may be worn.
What are the invitations like?
Invitations will be sent out on Friday 12 April. The white VIP invitations will see guests seated under the Cathedral's famous dome. A red or green stripe will show whether they are to sit on the port or starboard side. Other invitations are colour-coded relating to where guests are to be seated in the cathedral.
Are there any more details?
Flags will be flown at half mast on UK government buildings and British embassies from 8am to 8pm on the day of the funeral.
The working title for the funeral's operation plan is True Blue - which has drawn criticism from Labour's Andy Burnham for politicising the event.
Thatcher requested there should not be a flypast as she considered it a waste of money.
Lady Thatcher's family have asked that if people wish to pay their respects, they consider making a donation to the Royal Hospital Chelsea, rather than laying flowers.
Thatcher’s love of Elgar’s classical music – especially Pomp and Circumstance – is expected to be reflected in the service.
The Number 10 website will have a condolence page on which people will be able to write private messages for the Thatcher family.
The public will be unable to attend the funeral service itself but can line the route of the funeral procession from the RAF Church in the Strand to St Paul's Cathedral.
