Prince Harry and Meghan Markle are to reunite with the royal family later this year.
The Duke and Duchess of Sussex are reportedly set to return to the UK in June to attend the Trooping of the Colour, which is held in honour of the Queen's birthday on June 12.
A source told The Sunday Times newspaper: "The current plan is for the Queen's birthday parade to go ahead in London as normal, with the acceptance that it may need to be adapted depending on guidelines.
"The aspiration and the ultimate desire is to make it happen."
