Prince Harry has touched down in London town.

The Duke of Sussex, 40, arrived on his home soil Monday morning for the annual WellChild Awards — marking his first time in the UK since April, when he famously lost his bid for taxpayer-funded security protection.

The duke was seen departing from Los Angeles International Airport in the wee hours of Monday morning, the Sun reports.

His wife, Meghan Markle, did not join him on the trip, instead staying put in Montecito, Calif., with the pair’s two children Archie and Lilibet.

During his brief dash to the UK, the “Spare” author is rumored to be meeting up with his estranged father, King Charles.

The father-son duo’s alleged peace summit will mark their first in-person meeting in 20 months.

However, Harry — whose visit also coincides with the third anniversary of Queen Elizabeth II’s death — will not be meeting with his estranged brother, Prince William.

In fact, it’s been reported that the Prince of Wales, 43, has shut down any chance of a royal reunion by committing to a full diary of royal engagements on the days Harry is in the UK.

Kensington Palace has announced that the future king’s plate will be full with various official outings on Monday, Tuesday and Wednesday in a direct clash with Harry’s two confirmed events, GB News reports.

The Invictus Games founder will attend the WellChild Awards Monday night, followed by an appearance at the Community Recording Studio in Nottingham the following day.

There, Harry will announce a donation to the Children in Need charity.

William, for his part, will spend Monday in Sunningdale, England, to commemorate the life of his late grandmother, Queen Elizabeth II.

On Tuesday, the prince will visit Spiral Skills, a youth organization based in central London, which has received funding from the Homewards Fund foundation, which William had launched in June 2023.

The following day, the royal will visit a new mental health hub in Cardiff, Wales, which is run by the Jac Lewis Foundation. William and his wife, Kate Middleton, both backed the charity financially through their royal foundation.

A reunion between William and Harry had already seemed highly unlikely, given that the feuding brothers has not spoken to each other in years.

What’s more, insiders suggested that William had rejected his brother’s invitation to chat and strongly opposed his brother being granted any formal — or informal — audiences with members of the royal family.

“At the end of the day, as he’s (Harry) no longer a member of the institution, he doesn’t feel bound to de-conflict his diary with the institution,” a source told the Times of London.

Indeed, fundamental issues remain that prevent the royals from fully burying the hatchet.

“There are trust issues there, but the king misses his son [Harry],” the monarch’s former personal butler, Grant Harrold, exclusively told The Post.

“William is worried that with the stuff Harry has said, he could use it to his advantage again … like he’s already done. I think, sadly, they don’t trust him. It’s a shame, because Harry wants them to.”

In the days leading up to Harry’s arrival, the duke had reportedly come up with a list of demands from the monarchy that had reportedly left palace courtiers “reeling.”

The father of two reportedly barked out several requests that need to be fulfilled by the Windsor clan, according to top celebrity publicist Rob Shuter.

In his most recent Substack, Jennifer Lopez’s former p.r. honcho claimed that insiders close to Harry revealed some of the things on his alleged list.

Among those is “full security” for him and his family, “press control” that will be “coordinated by Buckingham Palace” and for the Duchess of Sussex to be treated as Her Royal Highness, “complete with bows and curtsies” in her presence.
