The prince appeared to be all smiles as he arrived at the 14th Invictus Games Foundation Conversation: From Policy to Practice event. The event will bring together leading experts, policymakers and members of the Invictus community to discuss issues affecting wounded, injured and sick service personnel and veterans. At the event, Harry will meet a number of people, including the UK minister for veterans and people, Calvin Bailey.

A trial began in January, with a ruling being made today. In the ruling, Mr Justice Nicklin said that all the claims against Associated Newspapers Ltd had been dismissed.

Speaking about Harry's "wary" appearance today, Judi told the Daily Express: “Prince Harry greets the UK press and public here like a man with the expectation of popularity and support.

“It is a wary-looking body language performance, but when his eyes hit the cameras, or he turns to wave, his facial expression suggests he is greeting friends.

“As he gets from the car for the short walk to the entrance, his shoulders are hunched, and his head is lowered, suggesting wariness.”

She continued: “His part open mouth suggests some tension here and when he does first smile it's a closed-lip 'suffering' smile that we usually see when someone is wanting to show a stoic and even brave approach.”

“His right hand is raised high for his 'hail' wave though, and it is this wave plus his other smile to the crowds or press that seem to form an 'aside' aimed at a friendly audience.

“Harry jogs up the steps as though unkeen to linger and his hands held near his waist suggest some inner tension as they form a partial barrier. But his 'over-the-shoulder' smile looks created for fans. His eyes are crinkled now in an eye smile and his mouth smile is a more natural, friendly one.”
