Heart-warming images of the Duke of Cambridge enjoying a laugh with a young cancer patient have been shared as the Prince marks his 10-year anniversary as president of the Royal Marsden Hospital.

The 34-year-old smiled as he helped take little Daisy Wood’s blood pressure during his visit to the Sutton centre earlier today (Tuesday, May 16).

Daisy, from Kingston, was tongue-tied when she met the Duke, but the pair bonded soon afterwards.

Her father Alistair Wood, 45, said: "It's particularly nice he's come around, it shows he's interested in the Royal Marsden and the patients, it gives a boost to everyone.

"And being a dad with two young children you can see how he relates very well to the children."

The Duke was then shown a £10 million MR Linac scanner, the first of its kind in the country, that combines radiotherapy treatment with traditional imaging and has the potential to allow tumours to be targeted more precisely.

After he peered into the small sot that a patient lies in as their body is scanned joked about the space.

He said: “I wouldn’t like to lie in there for too long, I’m not sure it’s as roomy as they say.”

Later the royal was reunited with radiotherapy aid Fiona Bragg, who took William under her wing when he shadowed staff at the hospital in 2005, two years before he became the institute’s president.

She recalled how she spent more than an hour showing the Duke how to check patients in, once they arrived at reception.

The 55-year-old said: "We just introduced him as William, he was really relaxed and friendly and spent a lot of time talking to the patients, not many people spotted him. One lady said he was a lookalike."
