Inside 'favourite' Sophie Wessex’s unique bond with the Queen

ok.co.uk:

Sophie, Countess of Wessex shared an exceptionally close bond with her mother-in-law, Queen Elizabeth II. The 57 year old, who is married to the Queen's youngest son Prince Edward, 58, was often described as Her Majesty's "favourite" relative, with her and Edward's daughter, Lady Louise Windsor, 18, also said to have been the late monarch's favourite grandchild.

Sophie, who also shares son James, Viscount Severn, 14, with Edward, grew even closer to her late mother-in-law last year, following the death of the Duke of Edinburgh.

The mum-of-two reportedly became the Queen's "rock" during the difficult time, and would regularly visit her and call her everyday.

Sophie would reportedly make the 10-mile journey from her home to Windsor Castle frequently, in order to spend time with Her Majesty.
