The Duke of Sussex will announce a substantial donation to Children in Need on Tuesday when he attends a charity event in Nottingham.
The donation is intended to help support work tackling violence and its effect on young people.
It is one of several engagements for Prince Harry during a visit to the UK, which has also prompted speculation on whether he might meet his father, King Charles.
The duke, who lives in the US with his wife Meghan and their children, was last in the UK in April for a court hearing over the level of security protection he receives from the government while here.
Harry will arrive in London on Monday to attend an awards ceremony for WellChild, which supports seriously ill children and their families. The prince has been a patron for 17 years.
“I am always privileged to attend the WellChild Awards and meet the incredible children, families and professionals who inspire us all with their strength and spirit,” he said announcing his return to the UK.
Tuesday’s event in Nottingham will be held held at the Community Recording Studio (CRS) in Nottingham, a charity that teaches film and video skills as well as music.
Harry’s visit to Nottingham is to build support and funding for community organisations.
He will hold a private briefing with Children in Need, the Police and Crime Commission, CRS and Epic Partners, and will have informal meetings with some of the young people he has met previously.
The duke will also watch live performances from artists, and make a short speech.
Buckingham Palace has not commented on the possibility of a meeting between the King and the duke during this trip. Nor has Harry and Meghan’s team.
But recently, there have been signs that tensions between father and son are easing, and that a reconciliation could be within reach.
His father was in Italy on a state visit during the prince’s April trip to London.
This time, the King will be in the UK. He has spent most of the summer in Scotland at his Balmoral Estate but is regularly travelling south for cancer treatment and some royal engagements. It leaves open the real possibility of father and son meeting in person.
