Prince Harry will be staying within a stone’s throw of Buckingham Palace during his upcoming trip to the United Kingdom, Express.co.uk has learned.

According to a well-placed source, the Duke of Sussex will be within a very short distance of his family’s main residence when he arrives in the capital for the WellChild Awards on September 30.

Express.co.uk is aware of where Prince Harry will be staying but has agreed to withhold the information for security reasons.

The source adds that although the prince has chosen to avoid staying at a royal residence, a meeting with his father King Charles has not been ruled out.

“The King is due to head to London in late September,” said the source. “The King and Queen will mark the 25th anniversary of the Scottish Parliament on September 28 and are then heading south.

“It’s not yet been decided if the King will go to London for a meeting with his doctors and possibly his son, or whether he will head straight to Highgrove.

“There are currently discussions ongoing about finding a mutually agreeable place in the diary.”

The last time King Charles and Prince Harry saw each other was in February when it was announced that the monarch had cancer and the prince flew from the US to see him for just 45 minutes.

When the Duke returned in May, the King was too busy to meet, although His Majesty did offer his son accommodation in one of the royal properties, contrary to reports. Harry chose to stay in a hotel instead.

It has been made clear by sources close to the Sussexes on a number of occasions that the prince is keen to reconcile with his father.

Royal sources revealed over the weekend that King Charles called his son on his 40th birthday to wish him a Happy Birthday.

This followed the monarch marking the milestone via a tweet on the official Royal Family X page, signalling the start of a thawing of frosty relations between the Sussexes and the Firm.

The source added that the King is keen to keep an open dialogue with his son and wants to maintain a relationship with his grandchildren, Prince Archie, five, and Princess Lilibet, three.

The Prince and Princess of Wales also marked Harry’s 40th with a surprise social media message on Sunday.

Buckingham Palace and the Sussexes have been approached for comment.
