The Duke of Sussex will begin a week of engagements having returned to the UK, starting with an event in London for the Invictus Games, his charity for injured military veterans.
On Tuesday he will also find out the result of a court case that the prince and others brought against Associated Newspapers, publishers of the Daily Mail, with claims of unlawful information gathering.
Prince Harry will be attending events alone, as his wife Meghan and children Archie and Lilibet are not in London because of security concerns.
There was a confused start to the visit, when Prince Harry’s team announced that an invitation to stay in Buckingham Palace had been accepted.
But that was rejected by the Palace, which said that the prince had been told on Saturday that he would not be able to stay, because he had not responded to the invitation in time.
Starting on Tuesday, there are five days of events to be attended by the prince, showing support for some of his UK charities, as well as raising support for the Invictus Games. This includes a visit to Birmingham later in the week, where they will be held this time next year.
His visit has coincided with the result being published on Tuesday of a court case against Associated Newspapers, which he has brought with a number of well-known figures, including Sir Elton John, Sir Simon Hughes, Liz Hurley, Sadie Frost and Baroness Doreen Lawrence.
They have claimed that the newspaper group, which publishes the Daily Mail and Mail on Sunday, used unlawful methods for getting information for stories – allegations that have been strenuously denied by the publishers.
This is the latest – and is expected to be the last – in a series of courtroom battles fought by Prince Harry against what he has seen as the dishonest practices of the UK press.
If the outcome of the case is that the judge supports some claims and rejects others, it is likely that all sides might claim victory.
