Prince Harry and Ms Markle thanked all those involved in their lavish wedding at the weekend as they released the official photographs from their big day.

"They feel so lucky to have been able to share their day with all those gathered in Windsor and also all those who watched the wedding on television across the UK, Commonwealth, and around the world," the palace said in a statement.

The new royal couple said they were "delighted" with the official portraits taken by Ms Alexi Lubomirski and thanked the public for their "generous messages of support".

Some 100,000 people were in Windsor for the ceremony and it was watched live globally, including by 29 million people in the United States.
