Party fit for a King! It’s a late night for William and Kate as they depart Clarence House close to midnight after Charles’s glittering 75th birthday bash… but was his biggest present his first phone chat with estranged son Harry in six months?

The Prince and Princess of Wales were seen enjoying a late night out as they departed Clarence House close to midnight after King Charles’s glittering 75th birthday party.But reports suggest the monarch’s biggest gift this year was the call he received from his youngest son, Prince Harry, who allegedly phoned to wish his father a happy birthday – their first phone call in six months.

Dressed to impress, Kate, 41, oozed elegance in an emerald Needle & Thread Alicia sequin-embellished recycled polyester gown, while Prince William, also 41, looked smart in a white shirt and jacket as he drove from the King’s London residence.They were joined at the monarch’s birthday celebration by his niece Princess Beatrice, Princess Margaret’s daughter Lady Sarah Chatto and Princess Anne’s daughter Zara Tindall and her husband Mike Tindall.

Looking effortlessly elegant, Zara, 42, stunned in Australian designer Rebecca Vallance’s £640 Eva dress, featuring a figure-skimming silhouette and dazzling pearl embellishment.Sources close to Harry told the BBC he would be calling his father, who does not own a mobile phone, for his birthday. According to The Sun, Charles is understood to have also spoken with his daughter-in-law Meghan Markle during yesterday’s call.

Charles and Harry are understood to have had minimal contact for months, particularly since the release of Harry’s tell-all memoir Spare, published in January, and a Netflix series, which was released the month prior to that.
