With the Queen's Platinum Jubilee celebrations just days away, Prince Harry and Meghan Markle's arrival in the UK is imminent.
The couple confirmed earlier this month that they would be coming to Britain for the bumper bank holiday weekend - and they will also be bringing their children three-year-old Archie and Lilibet, who is just days away from her first birthday.
As non-working royals, they are not expected at some of the Jubilee events but might play a role at others.
Meanwhile, the Sussexes will also mark a very important milestone while they are in the UK, which will reportedly see the Queen join them for a special party.
So what are Harry and Meghan's plans for their trip? Here we take a look at what we know so far...
When will they arrive and where will they stay?
It's unknown when Harry and Meghan will exactly arrive in the UK with Archie and Lilibet - but given Jubilee celebrations kick off on Thursday, it is likely to be imminent.
The family are expected to stay at Frogmore Cottage, their home on the Windsor estate where they lived before they quit as senior royals to move to the US.
The Sun reports that the property is currently empty as current tenants Princess Eugenie and her husband Jack Brooksbank are in Portugal.
Harry, 37, and Meghan, 40, had been expected to let the Frogmore Cottage lease expire after they left the UK for America, but they reportedly committed to a new 12-month rolling deal last month.
Royal insiders believe the move could mean that the Sussexes plan to spend more time in Windsor.
One insider told the Sun: “It is quite a signal that they aren’t going to disappear. They could easily give up Frogmore as their life’s now in California."

The Jubilee celebrations kick off on Thursday with Trooping the Colour - but so far, it is unknown what role, if any, Harry and Meghan will play at this event.
They could make an appearance in one of the horse-drawn carriages that make their way from Buckingham Palace to Horse Guards Parade.
However, it has been confirmed they will not be appearing on the Buckingham Palace balcony after the parade for the traditional RAF flypast as the Queen has limited balcony appearances to working royals only.
Joining the Queen on the balcony for Trooping will be Prince Charles, Camilla, the Duchess of Cornwall, the Duke and Duchess of Cambridge, the Earl and Countess of Wessex, the Princess Royal, the Duke and Duchess of Gloucester, the Duke of Kent, Princess Alexandra, and Vice Admiral Sir Tim Laurence.
Also set to appear for the historic occasion will be Prince George, Princess Charlotte and Prince Louis and the Wessexes’ children Lady Louise Windsor and James, Viscount Severn.
Service at St Paul's Cathedral
However, on Friday, Harry and Meghan are expected to join the Queen and the rest of the Royal Family at a service of thanksgiving at St Paul's Cathedral.
According to the Telegraph, as well as Harry and Meghan being expected to attend the service at St Paul's, Prince Andrew is also expected to be among those at the service - with the entire Royal Family also there.
This means that all of the Queen's children and grandchildren could be at the event - and some of her great-grandchildren may also reportedly attend.
Among the youngest royals that could be there are Prince George, Princess Charlotte and Mia Tindall although Harry and Meghan's two children Archie and Lilibet are unlikely to be there, given their young ages.
Lilibet's birthday
During their stay in the UK, Harry and Meghan will be marking a very special day - daughter Lilibet's first birthday.
She turns one on Saturday - and as she's never been brought to the UK yet - she has not met the Queen, her grandfather Prince Charles or many other of her royal relatives.
However, reports have suggested that her birthday will be the day the couple will finally formally introduce Lilibet to the Queen.
On Saturday, it is the Epsom Derby - an event that the Queen often attends, but it has been reported she may no longer be planning on going.
Instead, it has been reported that she will see Lilibet and be invited to a birthday party for her - and will be reunited with Archie, who she has not seen since he was a baby.
It comes as the 96-year-old monarch, who has been suffering mobility problems, is said to want to pace herself during her milestone celebrations, with her daughter Princess Anne representing her at the racecourse instead, The Sunday Times reported.
Buckingham Palace declined to comment, saying the Queen’s attendance at events would not be confirmed until closer to the time.
However, the Sun has reported that instead, Her Majesty will see her great-granddaughter, whose name honours the monarch.
