Queen Elizabeth’s biggest regrets revealed after death

The Queen documentary also reflects on later attempts to balance tradition with public engagement, including high-profile moments such as the Queen’s appearance alongside Paddington Bear during her Platinum Jubilee celebrations.

Queen Camilla, 78, appears in the documentary, highlighting Elizabeth’s enduring devotion to duty.

She said: ‘I think duty has trumped everything. I don’t think I’ve ever seen anyone have such a sense of duty as she does.”

Another source familiar with royal history said the decision to allow cameras into the palace remains one of the most debated choices of Elizabeth’s reign, and one she “has the deepest regrets.”

The insider added: ‘There is a strong argument that it humanized the monarchy at a crucial time, but it also created expectations about access that could never be met without consequences.

“This documentary revisits the late queen’s legacy and presents a portrait of a ruler making unprecedented social and media changes – and grappling with decisions that reshaped the institution she spent a lifetime trying to preserve.

“But make no mistake: humanizing the monarchy by letting the cameras in was perhaps her biggest regret.”
