The Duke and Duchess of Sussex will make their first joint official visit to the county that inspired their royal titles.

Harry and Meghan will head to the south coast on Wednesday on a whistle-stop tour of Sussex.

On a busy day of engagements they will arrive first in West Sussex, at Edes House in Chichester.

The duke and the US-born former actress will view the rare Sussex copy of the American Declaration of Independence.

Then they will arrive in Bognor Regis to officially open the University of Chichester’s Engineering and Digital Technology Park.

In the afternoon the couple will travel to East Sussex.

Harry, who was given the title the Duke of Sussex by the Queen on the morning of his wedding, will tour Brighton’s historic Royal Pavilion with the duchess.

Afterwards they will visit the nearby Survivors’ Network, a charity that supports victims of sexual violence and abuse.

The couple end the tour in Peacehaven, meeting youngsters at the JOFF Youth Centre and hearing about their work on mental health and wellbeing.

While in Chichester and Brighton, the pair will also spend time meeting the crowds gathered to greet them.

Before Harry, the title the Duke of Sussex was last used 175 years ago by Prince Augustus Frederick – an eccentric son of King George III who had his two marriages deemed illegal.

Meghan is the first Duchess of Sussex.
