They are known for defying royal protocol with public displays of affection and today Prince Harry and his new wife Meghan looked enamoured as ever as they kissed during the prize presentation at the end of a charity polo game.

The Duchess, 36, was eager to congratulate her husband after his Sentebale St Regis team won 5-4 over Royal Salute, with the Prince scoring two goals at the Sentebale Polo Cup - held to raise funds for Harry's charity which supports young people with HIV and Aids in Lesotho.

Meghan, 36, who was channelling 50s chic in a £2,357.50 (NZD $4553) navy dress by Carolina Herrera, gave the team's captain, international polo legend and male model, Nacho Figueras, a friendly peck on each cheek - but only had eyes for one man, Prince Harry.

As they walked away from the prize presentation Meghan could be seen affectionately rubbing the prince's back before the pair walked off hand in hand, showing that the honeymoon period between the newly-weds certainly hasn't cooled off.

And if further proof were needed, Harry's close friend and fellow player Nacho said afterwards: "The Duchess is lovely and wonderful. I'm very happy for Harry. They are both lucky to have found each each other and I am very excited about this new chapter in his life."

Figueras said Meghan had been excited to present the prize at today's match, joining a long list of royal ladies - including Diana, Princess of Wales - to hand out a polo trophy.

"She said she enjoyed the game. She watched the game with my wife which was wonderful because she could learn more about the game," he explained.

"It was great that I got to play with Harry because we normally play against each other. Harry played great. They are very, very happy together."

He laughed at suggestions that Meghan wanted to learn to play polo, saying: "What are you reading?! Do you use Google or what? Sometimes it doesn't work!"

Former actress Meghan is becoming well versed in the sport and attended the Audi Polo Challenge in Ascot to cheer on her man as he competed with his brother at the end of June, accompanied by her friend Serena Williams.

And the newlyweds made their first appearance as a couple when they attended the Audi Polo Challenge at Coworth Park, Berkshire, in May last year where they were spotted embracing in the car park.
