The Duke and Duchess of Sussex are due to appear in a much-anticipated television interview with Oprah Winfrey.
It will air in the US on Sunday and in the UK on ITV on Monday at 21:00 GMT.
Who are the members of the UK’s Royal Family and how does it work?
Queen Elizabeth II has been the UK’s head of state since 1953 and has ruled for longer than any other British monarch. She is also the head of state for 15 other Commonwealth countries.
The 94-year-old monarch and her husband, the Duke of Edinburgh (Prince Philip), who is 99, have four children, eight grandchildren, and nine great-grandchildren.
Other members of the Royal Family include:
Only those born into the Royal Family can be in line to the throne.
However, those who marry a royal also become a member of the Royal Family.
They are given a title when they marry. For example, Lady Diana Spencer became Princess of Wales when she married Prince Charles in 1981.
Royal weddings often take place at some of the oldest and grandest places, and attract huge crowds.
The Queen and Prince Philip were married in 1947 at Westminster Abbey, which was founded in 960 AD and is next door to the Houses of Parliament.
More than six decades later, in 2011, crowds lined the streets outside the Abbey to celebrate the marriage of her grandson William, to Catherine Middleton. They became the Duke and Duchess of Cambridge.
Other royals have exchanged vows at St George’s Chapel at Windsor Castle, which is more than 900 years old.
The weddings there include Prince Harry’s to Meghan Markle in 2018.
A number of senior royals have been born at St Mary’s Hospital in London.
Princess Diana gave birth to Prince William and Prince Harry there, and the Duchess of Cambridge her three children: Prince George, seven, Princess Charlotte, five, and Prince Louis, two.
Both women were photographed with their husbands and babies outside the hospital.
The newest addition to the Royal Family is August Philip Hawke Brooksbank, son of Princess Eugenie and her husband Jack Brooksbank. He was born on 9 February 2021.
The British government is called Her Majesty’s government, but the Queen has almost no political power.
The Queen meets with the prime minister once a week, as a reminder of her place in government, but the prime minister doesn’t seek her approval for policies.
The Queen and other senior royals carry out official engagements.
Family members also represent her in visits to other countries. For example, the Duke and Duchess of Cambridge carried out an official visit to the Republic of Ireland last March.
Many are patrons for charities, and some have established their own – such as the Duke of Edinburgh’s Award Scheme for young people.
They have close ties to the armed forces. Prince William served in the Royal Air Force and Prince Harry served in the Army.
No. Last year, Prince Harry and Meghan, Duchess of Sussex, announced they would step back and work to become financially independent.
Buckingham Palace confirmed the couple will return their honorary military appointments and royal patronages, which will be redistributed to working members of the Royal Family.
The Duke of York (Prince Andrew) stepped away from royal duties in 2019.
This was after an interview he gave to the BBC about his relationship with sex offender Jeffrey Epstein.
Every year, the UK government gives the Queen a single payment called the Sovereign Grant.
This is based on 25% of the Crown Estate’s revenue from two years previously. The Crown Estate is an independent commercial property business. It includes the 4,800-acre Windsor Great Park and the Ascot racecourse in Berkshire, but is mostly made up of residential and commercial property.
The Sovereign Grant, which is £85.9m for 2020-21, supports official royal duties and maintains occupied royal palaces.
Prince Charles receives an income from the Duchy of Cornwall, a vast portfolio of property and financial investments, which brought in £22.3m last year.
The Queen’s official London home is Buckingham Palace.
She usually spends weekends and a month over Easter at Windsor Castle in Berkshire. However, she and Prince Philip have lived there throughout the pandemic.
Prince Charles and the Duchess of Cornwall live in Clarence House – less than half a mile from Buckingham Palace – when they are in London.
Prince William and Catherine, Duchess of Cambridge, also live nearby – in Kensington Palace.
