What is Queen of the World about and which royals are in it?
In this behind-the-scenes look at the royal family with a focus on their Commonwealth projects, ITV has managed to secure a rare amount of access to the monarchy.
Viewers follow various British royals, including Meghan Markle, who revisits her wedding dress ahead of a new exhibition, and a jokey Prince Harry, who greets eight young hospitality professionals on work experience at Buckingham Palace.
There are also private home movies to pour over — and a glimpse inside Rideau Hall, Ottawa: the Queen’s Canadian residence.
