As the King's Coronation draws closer, members of the royal family will be busy preparing for the historical day ahead with Kate Middleton said to be hitting the gym and helping her children. The Princess of Wales will play a key role in her grandfather-in-law's coronation as the next Queen Consort in line of succession, alongside husband, Prince William who is heir to the throne. As preparations and rehearsals are well underway for the day, historian, writer and broadcaster Tessa Dunlop spoke exclusively to OK! and said “Kate will be working out and in that gym" in the days leading up to the coronation.
