The Queen had a close relationship with all of her grandchildren and great-grandchildren, but a break of royal protocol for Meghan Markle proved Prince Harry had a "special place" in her heart, an expert has claimed.
Shortly after the couple's engagement in 2017, the royals all travelled to Sandringham for their annual Christmas break.
However Meghan, who was living in the UK at the time, shouldn't have been on the guestlist as royal partners aren't normally allowed to attend until they have officially married into the family.
