The King has left hospital after undergoing treatment for an enlarged prostate.
He will not carry out royal engagements for up to a month as he recovers from the surgery, Sky News understands.
Sky’s royal correspondent Laura Bundock said there will now be a “period of recuperation” for the King, though he can attend to red boxes with government papers.
The monarch, 75, was admitted to the London Clinic hospital on Friday morning with the Queen at his side.
It is the same hospital where the Princess of Wales was recovering after undergoing abdominal surgery.
The princess left earlier on Monday to recover at home in Windsor. It is understood the King visited her ahead of his own treatment.
When the Queen left the hospital just after 3pm on Friday she told people her husband was “doing well”. She visited him again on Saturday and earlier on Monday.
The King arrived in London from Norfolk on Thursday afternoon ahead of the procedure after a couple of behind-the-scenes official duties.
He was diagnosed with the benign condition on 17 January after going for a check-up when he was experiencing symptoms.
It is understood the King shared details of his diagnosis to encourage other men who may be experiencing symptoms to get checked in line with public health advice.
NHS England said the “enlarged prostate” page on the NHS website received one visit every five seconds on the day the King’s diagnosis was announced, with further huge boosts in visits in the following days.
