Kate Middleton has made her first public appearance since her cancer diagnosis at a Buckingham Palace balcony appearance with the British royal family in honour of Britain's King Charles' official birthday.

Kate looked relaxed during her first day in the spotlight following her cancer diagnosis for the traditional Trooping the Colour ceremony, where her youngest child Louis stole the show again.
