Prince Harry is to attend the Army Navy rugby match at Twickenham on Saturday.
He is Patron of the Invictus Games Foundation, which is the official charity of the day for this year’s match.
This year sees the 100th fixture since the unions were formed and marks the culmination of the annual Inter-Services Competition.
The Prince will be joined on the day by competitors from the 2014 and 2016 Invictus Games, as well as some of those hoping to be selected for the third Invictus Games in Toronto.
Friends and family have also been invited as the Invictus Games Foundation wants to recognise the contribution this close support network plays in a competitor's recovery journey.
