Prince Harry has made a surprise trip to London and is at the High Court to attend a hearing in his latest legal claim.
The Duke of Sussex is among a number of high-profile individuals who have brought a case against Daily Mail publisher Associated Newspapers over alleged unlawful information-gathering at its titles.
As he arrived at the Royal Courts of Justice this morning flanked by security, a smiling Harry bid waiting photographers and reporters a "good morning" and almost walked into one snapper before he entered the building.
It is believed to be the first time Harry has been back in the UK since the late Queen's funeral in September.
His surprise return comes nearly three months after he laid bare his troubled relationship with his father King Charles and brother Prince William in his controversial autobiography Spare.
The hearing today was due to coincide with Charles and Queen Camilla's state visit to France, which was due to start yesterday but was shelved due to unrest in the country.
But according to the Telegraph, Harry is not expected to meet up with his father while in the UK - even though the King was informed of his visit - as he is "busy".
Buckingham Palace said the King was not in Windsor or London and would be leaving for a state visit to Germany on Wednesday morning.
The Prince and Princess of Wales and their children Prince George, Princess Charlotte and Prince Louis are not currently in Windsor either because of the youngsters' school Easter holidays.
Harry and Meghan have been asked to vacate their UK home Frogmore Cottage on the Windsor estate, in a move sanctioned by the King, meaning Harry could spend some of his time packing up any remaining possessions.
The duke is also taking legal action against the Home Office over security arrangements when he is in the UK, raising questions about his own security provisions during this visit.
His visit also comes amid questions over whether he and wife Meghan Markle will be in the UK in just six weeks time to attend the Coronation of his father at Westminster Abbey.
It has been confirmed the Sussexes have been in contact with Buckingham Palace regarding attending the historic event - but they have not confirmed if they are attending or not. The day also clashed with their son Archie's fourth birthday.
At the High Court today, the Daily Mail publisher is bringing a bid to end claims brought by people including Harry, Sir Elton John and Baroness Doreen Lawrence over alleged unlawful activity at its titles.
The group of high-profile individuals, also including Sir Elton’s husband David Furnish and actresses Liz Hurley and Sadie Frost, announced in October they were bringing claims for misuse of private information against Associated Newspapers Limited (ANL).

Their lawyers said at that time the group have "become aware of compelling and highly distressing evidence that they have been the victims of abhorrent criminal activity and gross breaches of privacy" by ANL, which is also the publisher of The Mail On Sunday and MailOnline.
In a statement announcing the launch of the legal action, released by Hamlins law firm, it was alleged the unlawful acts included hiring private investigators to secretly place listening devices inside cars and homes and the recording of private phone conversations.
The publisher hit back at the allegations, describing them at the time as "preposterous smears" and a "pre-planned and orchestrated attempt to drag the Mail titles into the phone-hacking scandal".
A spokesperson for ANL also said the allegations were “unsubstantiated and highly defamatory claims, based on no credible evidence”.
A four-day preliminary hearing at the Royal Courts of Justice in London is due to begin today, which is set to include ANL's bid for the claims to be dismissed without a trial.
