Prince Harry has been to Windsor Castle where he laid a wreath and privately paid respects to the late Queen.
The Duke of Sussex arrived in the UK earlier today and visited the royal residence where he left flowers for the former monarch.
Harry is in London for the annual WellChild Awards before travelling to a community recording studio in Nottingham on Tuesday.
It is not known whether the duke, who is estranged from his brother, Prince William, and has a troubled relationship with his father, the King, will meet up during his stay.
Harry and Charles last met face-to-face more than a year-and-a-half ago after the duke rushed to see the King following his cancer diagnosis.
It is the first time Harry, who lives in California with wife Meghan Markle, has returned to the UK in five months.
The duke wants to bring together key stakeholders, influencers and potential funders for WellChild.
