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.

It marks the third anniversary of the late Queen's death.

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.

But the visit has fuelled speculation they will hold a reunion.

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.

Today, the Princess of Wales also joined her husband to pay respects to Queen Elizabeth II.

Kate and William visited the National Federation of Women's Institutes in Sunningdale, Berkshire.

It marks Kate's third engagement in five days after she visited the National History Museum's gardens last Thursday before watching the Red Roses beat Australia 47-7 in their women's World Cup match in Brighton on Saturday.

It is the first time Harry, who lives in California with wife Meghan Markle, has returned to the UK in five months.

In May he lost a long-running legal battle with the Home Office over changes to his security arrangements.

The duke wants to bring together key stakeholders, influencers and potential funders for WellChild.

Later today Harry will attend the charity's awards ceremony in London as its patron, a position he has held for 15 years.

He will make a speech, meet and talk to seriously ill children and their families. The duke will also present an award to an "inspirational child" aged between four and six.

Ahead of the visit, Harry said: "For 20 years these awards have highlighted the courage of young people living with complex health needs and shone a light on the devoted caregivers - family and professionals - who support them every step of the way.

"Their stories remind us of the power of compassion, connection and community."
