Prince William, the Duke of Cambridge, on Tuesday (May 13) welcomed celebrities and philanthropists to Windsor Castle just outside London for a charity dinner event celebrating the work of The Royal Marsden.
William is the president of The Royal Marsden, which is the largest comprehensive cancer centre in Europe and known for research into potential treatments.
Celebrity guests attending the charity dinner included actresses Margot Robbie, Helena Bonham-Carter, Emma Watson and Benedict Cumberbatch among others, as well as models Kate Moss and Cara Delevingne, all of whom were joined by representatives from The Royal Marsden, Chairman Ian Molson and Chief Executive, Cally Palmer.
The Duke, appearing at the event without his wife Catherine, the Duchess of Cambridge, also known as Kate, also marked the contribution of fashion designer Ralph Lauren, who is entering a new philanthropic partnership with The Royal Marsden.
Speaking before dinner, William praised the work and status of The Royal Marsden.
"I am exceptionally proud to be president of The Royal Marsden, an incredible hospital and a world class cancer centre carrying out groundbreaking work, influencing the treatment of cancer, both nationally and internationally," he told guests.
"I am enormously grateful to Ralph Lauren for his generosity and to all of you who so kindly support the hospital. You should know that what you do saves lives and gives hope to thousands of people," he added.
Kate and William recently celebrated three years of marriage on April 28.
