Prince Harry's inaugural Invictus Games will officially open tonight with a military-themed ceremony at the home of the London 2012 Olympics.
The opening ceremony for the Games for injured servicemen and women will feature an performance of the official anthem penned by Coldplay's Chris Martin as well as a flypast from the Red Arrows.
The 5,000-strong audience will include Prince Harry, the Duke of Cambridge, Prince Charles and the Duchess of Cornwall.
It is not known whether the Duchess of Cambridge will attend after she announced earlier this week that she is suffering from acute morning sickness with the pregnancy of her second child.
Prince Harry's Invictus Games is hailed a success as it closes with star performances from the Kaiser Chiefs, Ellie Goulding and Diversity.
Prince Harry led the royals in a game of wheelchair rugby, dubbed Murderball, on the second day of the Invictus Games.
