UK prime minister says he is in regular contact with the monarch and wishes him a full recovery
The Duke of Sussex has cleared his diary to fly to the UK to be with his father.
Prince Harry’s black Range Rover was pictured arriving at a private terminal at Los Angeles International Airport before he boarded a flight due to land around midday, according to the Sun.
Buckingham Palace announced on Monday that the king had been diagnosed with cancer and is already receiving treatment that will prevent him from undertaking public duties for the immediate future.
The type of cancer the king was diagnosed with has not been revealed but Buckingham Palace said it was not prostate cancer.
The cancer was discovered when the 75-year-old monarch recently underwent treatment at the London Clinic for a benign enlarged prostate.
The king returned to London from Sandringham on Monday morning to begin treatment as an outpatient.
Buckingham Palace said the king “remains wholly positive about his treatment”.
He began regular outpatient treatments on Monday, and although he has been forced to postpone public-facing engagements, he will continue with his constitutional role as head of state, including paperwork, his red boxes and private meetings.
The king personally informed both his sons, the Prince of Wales and the Duke of Sussex, of his diagnosis, as well as his three siblings, the Princess Royal, Duke of Edinburgh and Duke of York.
Prince Harry had spoken with his father about his cancer diagnosis and would be travelling to the UK to see him in the coming days, the Office of the Duke and Duchess of Sussex confirmed.
The king was last seen in public at Sandringham in Norfolk on Sunday, where he attended a church service with the queen, which was the first time he had been seen since he was discharged from the London Clinic.
The Palace has called for the king’s privacy to be respected, especially during his treatment, but said he wanted to make his diagnosis public because of his long-running support for cancer charities.
