The Duke and Duchess of Sussex will be attending the largest Royal Family reunion since their wedding next week, as the Queen’s relatives gather to celebrate her Platinum Jubilee.
The service, which will be held at St Paul's Cathedral on Friday 3 June, will mark the monarch's 70 years on the throne.

The thanksgiving service will be the only public event of the four-day celebration.
It is said that the Queen is keen to attend the service although her attendance will be confirmed on the day.
Palace aides have confirmed that the monarch has been facing "episodic mobility problems" since the Autumn.
