King Charles, Prince William seen returning to duties as wild rumors over royals’ health swirl

King Charles has made a defiant return to royal duties just days after baseless reports of his death surfaced online.

The monarch, 75, appeared chipper as he arrived in a limousine at Clarence House Tuesday morning after spending time at Windsor Castle in recent days.

Charles was then taken to Buckingham Palace, where he hosted a handful of veterans of the Korean War to mark the 70th anniversary of the conflict.

Charles, who is currently in the midst of his outpatient cancer treatment following his diagnosis in February, met with veterans Alan Guy, Mike Mogridge, Brian Parritt and Ron Yardley during the private audience.

Later, the king’s family will step in to host a reception for around 200 Korean War veterans in the palace’s Bow Room.

His sister Anne, the Princess Royal, will host the event alongside Sophie, the Duchess of Edinburgh.

Princess Anne will deliver a speech about the war on behalf of the king.

Charles’ appearance will help to quell the ongoing rumors about his health that have been sending royalists into overdrive in recent weeks.

Elsewhere on Tuesday, Prince William was seen visiting housing initiatives in Sheffield, north England, to promote his project to alleviate homelessness.

The Prince of Wales, 41, has long been an advocate for helping the homeless, and has done work for various charities through the Royal Foundation’s Homewards program.

During his visit, William made some remarks about Middleton.

When the topic of childhood was brought up,  William said, “That’s my wife’s area, she needs to be sat here.”

When a well-wisher told William that he sent Middleton a “get well” card, William also replied, “You really are very kind.”

William’s appearance Tuesday comes just days after he was spotted visiting a farm shop with his wife, Kate Middleton.

Palace sources have exclusively told The Post that footage of the Prince and Princess of Wales out and about should be enough to put an end to wild conspiracy theories about her health.

Charles, for his part, has been taking a slight step back from royal engagements in recent weeks since being diagnosed with cancer.

Despite that, the king is keen to attend his upcoming Trooping the Colour celebration in June, but palace sources say he may stray from tradition ever so slightly.

Sources claim that Charles could be driven in a carriage to the June 15 ceremony rather than riding horseback — something he would otherwise be expected to do.

Typically, Charles would ride on horseback from Buckingham Palace to Horse Guards Parade in St. James Park.

However, given his ailing health, the monarch could be driven to the parade in a carriage so that he could watch the ceremony from a podium.
