The Queen has said the King is doing “extremely well under the circumstances” after his cancer diagnosis, as she celebrated the work of charities at Salisbury Cathedral.

Camilla left Charles at Sandringham to fulfil her royal engagement tonight and among the first people she met were medical staff from Wiltshire Air Ambulance.

Ben Abbott, 40, a critical care paramedic, said: “I do hope His Majesty is doing well Ma’am, we’re all really sad to hear the news.”

Camilla replied: “Well he’s doing extremely well under the circumstances.

“He’s very touched by all the letters and the messages the public have been sending from everywhere – that’s very cheering.”

A night in a London hotel, then he was back on a plane to the States, leaving the nation to wonder if those brief moments with the man he says he’ll “always love” were enough to begin repairing their fractured relationship.

After the turbulence of the last few years, with Harry quitting his royal role and making a slew of damaging allegations about his family, he certainly can’t turn to his brother, the Prince of Wales, for mutual comfort during this worrying time. The pair are not believed to have spoken at all since Harry’s memoir Spare, in which he described William as his “arch nemesis”, was published.

Prince Harry has flown home to LA following a 26-hour visit to the UK that saw him reunite with his father for less than an hour after his shock cancer diagnosis.

The Duke of Sussex spent almost as much time in the air as he did in England, on what was his first visit to his homeland since September.

On Wednesday night, he broke his public silence to issue a statement to mark the 50th anniversary of independence of the former British colony Grenada.

Harry, 39, made no mention of his father and his cancer diagnosis during his speech, which saw him hand out the Walter Payton Man of the Year award to Pittsburgh Steelers defnder Cameron Heyward.

The latest stage of phone-hacking claims featuring the publisher of the Daily Mirror and the Duke of Sussex is set to take place at the High Court.

In December, a judge ruled that phone hacking became “widespread and habitual” at Mirror Group Newspapers (MGN) titles in the late 1990s and was practised “even to some extent” during the Leveson Inquiry into press standards in 2011.

Mr Justice Fancourt also concluded that Harry’s phone was hacked “to a modest extent” by MGN, awarding him £140,600 in damages.

The Duke of Sussex has appeared at the NFL Honours in Las Vegas to present an award, just days after the King revealed his cancer diagnosis.

Harry appeared at the event to present Pittsburgh Steelers defensive lineman Cam Heyward with the Walter Payton Man of the Year Award.

It comes after Harry flew thousands of miles from his Californian home to be at the King’s side on Tuesday, meeting with his father for around 45 minutes at Clarence House.

Buckingham Palace officials have announced that King Charles, 75, has been diagnosed with a “form of cancer” and is currently undergoing treatment.

In the 5 February announcement, the palace said that the King “is grateful to his medical team for their swift intervention, which was made possible thanks to his recent hospital procedure”.
