The Duke and Duchess of Sussex have wished "health and healing" to Kate Middleton after she announced her cancer diagnosis.

Prince Harry and Meghan Markle sent their well wishes to the Princess of Wales as she takes an extended break away from the public while undergoing chemotherapy.

In a statement released yesterday evening, Harry and Meghan said: “We wish health and healing for Kate and the family, and hope they are able to do so privately and in peace.”
