Prince William is at a crossroads. He hasn't spoken publicly yet about the King's cancer diagnosis, but he must have been thinking long and hard about it since his father gave him the news.

For anyone, this is shocking news, something difficult to digest. It's a situation in which both parent and child want to protect the other.

But it must feel to Prince William that the responsibilities lying ahead of him are closer than ever.

Prime Minister Rishi Sunak went beyond what Buckingham Palace had revealed with the reassurance that the King's cancer had been caught at an early stage.

So there will be every expectation of a good recovery, with the King "wholly positive" and getting on with his meetings and paperwork that are part of his role as head of state.

Nonetheless, it must be a reminder to Prince William how his own role will change, not least in the short term, as he takes on more engagements while the King recuperates.

It won't be a brotherly double-act, with sources suggesting that when Prince Harry is in the UK there are no plans for him to meet his brother.

If Prince William has to step up and take on more royal duties, it will be a chance to see how differently he might do things in future.

Prince William will return to public duty for the first time since his wife Catherine, the Princess of Wales, underwent a medical procedure and since the King's cancer diagnosis.

The Prince of Wales is expected to take over some of the King's duties while his father receives treatment.

He will perform an investiture ceremony at Windsor Castle later this morning.

Among those receiving an honour is Ellen White, the England women's football team's record goalscorer who was key to the Lionesses' victory at the Euros in 2022.

William will then attend a fundraiser for London's Air Ambulance Charity in central London later this evening.

Catherine left hospital last Monday and returned to her home in Windsor following her abdominal surgery on 16 January.

At the same private hospital in London, King Charles received treatment for an enlarged prostate - which led to his cancer being discovered.

The prevalence of cancer has been discussed widely since the King's diagnosis was announced.

He's one of around 1,000 people in the UK who are diagnosed with cancer on any given day, and stands among the three million people currently living with the disease.

Prostate cancer is the most common type of cancer among men in the UK - we've been told this isn't the King's diagnosis. For women, it's breast cancer.

Lung and bowel cancers are the next most common to be diagnosed.

The NHS tells us, external that some signs of cancer include a lump that suddenly appears on your body, unexplained bleeding and/or changes to your bowel habits. There are plenty of other symptoms, too, so if anything is concerning you, you should check in with your GP.

Here's a timeline of the King's recent health treatments in the lead up to his cancer diagnosis:

• 17 January: Buckingham Palace announces that King Charles will attend hospital for treatment for an enlarged prostate the following week
• 26 January: The King receives his treatment after being admitted to the London Clinic in the morning. Queen Camilla says her husband's "doing well"
• 29 January: The King leaves hospital after three nights. The Palace says he'll have to postpone his public engagements "to allow for a period of private recuperation"
• 31 January: Queen Camilla says her husband is "doing his best" after hospital treatment
• 4 February: The King and Queen attend church in Sandringham, with Charles waving at well-wishers, in his first public outing since treatment
• 5 February: The Palace announces that the King has been diagnosed with a "form of cancer" discovered during his recent treatment. The type of cancer has not been revealed, but the Palace says it's not of the prostate and the King has started "regular treatment"

Prince Harry's return to the UK to see King Charles following his cancer diagnosis leads many of Wednesday's front pages.

The Telegraph says the Duke of Sussex landed on Tuesday after a 10-hour flight from Los Angeles and was driven straight to Clarence House, the King's home in London, for a meeting with his father.

The Guardian reports Harry travelled alone, with the Duchess of Sussex staying in the US with their two children.

King Charles delayed his trip to Sandringham to see Prince Harry, the Sun says. The paper reports that the King was "doing very well", according to its sources.

A new image of the King and Queen - the first taken since Charles's cancer diagnosis was made public - is on most front pages.

The Mirror says the King looked "emotional" as he and the Queen smiled and waved at royal fans during their first public outing since his diagnosis was announced.
