Alan Titchmarsh presents a truly intimate portrait of the Queen by those closest to her. The Duke of Cambridge speaks of her as 'grandmother first, queen second', while the Duke of York and the Princess Royal talk about what it was like to grow up 'above the shop' at Buckingham Palace with a mother who had to juggle the pressures of her job with the responsibilities of a young family. The programme also features private archive footage of the Queen as a young girl as well as rare access to family letters
