Prince William made his official return to his royal duties on April 18 by working with Surplus to Supper — a charity organization that delivers, sorts and repackages unused food for communities in need — and provided an update about Kate’s cancer treatment while interacting with the organization’s employees.

During the tour of the Surplus to Supper facilities, volunteer Rachel Candappa gave him two special cards, one for King Charles and one for Kate Middleton. According to Express, William looked “visibly moved” and told her, “Thank you, you are very kind.” Speaking with the outlet, Candappa added, “I said take care of her and he said ‘I will.’”

Royal reporter Rebecca English corroborated the claims, sharing videos from William’s day at work to X. “Prince William promised to ‘look after’ the Princess of Wales as he made his first public appearance since her cancer announcement and was handed get well soon cards addressed to the King and Kate. He also delivered food surplus packages with volunteers from Surplus to Supper,” she tweeted.

The visit to Surplus to Supper marked William’s first engagement since Middleton revealed her cancer diagnosis on March 22. The royal was with Middleton and their three children, Prince George, Princess Charlotte, and Prince Louis, for three and a half weeks following the news and through the Easter holiday.

“Having William by my side is a great source of comfort and reassurance too,” she said in her announcement video, adding, “We hope that you’ll understand that as a family, we now need some time, space, and privacy while I complete my treatment.”
