Could Prince Harry return to Britain in May? Duke may attend 10th anniversary service of the Invictus Games in London, source claims – after flying visit to cancer-stricken King Charles

Prince Harry could return to Britain just weeks after a hasty visit to his father King Charles, who was recently diagnosed with cancer.

The Duke of Sussex's trip to London lasted just 24 hours but the royal, 39, was able to return within weeks for a service to mark the 10th anniversary of the Invictus Games.

Harry launched the games in March 2014 at the Copper Box Arena in London and the 10th anniversary celebration will take place at St Paul's Cathedral.

A source said The Express: 'Harry has indicated that he would like to return for a British Invictus Games and we understand that the Games have always had the support of the rest of the Royal Family.'

Prince Harry flew to London from LA last week to visit his father King Charles, who was recently diagnosed with cancer

Harry returned to Heathrow last Tuesday, just 24 hours after being driven from the same airport to Clarence House under a police escort the day before.

The Duke flew to London on a ten-hour flight from Los Angeles, arriving at the royal residence at 2.42pm before spending around 45 minutes with Charles.

However, despite his return to LA, Harry and Meghan were not seen at last night's star-studded Super Bowl match in Las Vegas, despite the Duke's recent appearance at an NFL awards event.

It was rumored that the couple would join the many A-list celebrities – including Taylor Swift, Beyonce, Jay Z and Sir Paul McCartney – at the biggest American Football game of the year, which took place in Las Vegas.

But the pair were noticeably absent from the festivities ahead of a trip to Canada for the opening ceremony of the Invictus Games in a few days.

Last night the Kansas City Chiefs won with a last-minute overtime in a nail-biting game against the San Francisco 49ers.

Last week, Prince Harry made an appearance at the NFL Honors, also held in Sin City, after returning from a short trip to Britain to visit his cancer-stricken father.

During the awards ceremony, which took place just 24 hours after his flying visit to London, Harry presented the prestigious Walter Payton NFL Man of the Year Award to Cameron Heyward of the Pittsburgh Steelers.

Daily Mail Diary editor Richard Eden said last week that Harry and Charles held a 'brief meeting' before the king returned to Sandringham.

Royal commentator Richard Fitzwilliams also said: 'I am sure Harry will now put the past aside on this serious issue. The Royal Family – including the Sussexes – is so important that everyone is moving in the right direction.”

Kristina Kyriacou, the king's former press secretary, added: 'Charles loves Harry. He didn't want this alienation. If bad news comes with good news and Harry and the King, the Queen and his brother are reunited – how wonderful.”

The king was taken by helicopter to London from Sandringham on Monday to begin outpatient treatment for cancer.
