Prince Charles and Princess Anne Arrived at Mother Queen Elizabeth's Side Before She Died

Queen Elizabeth's two eldest children arrived at Balmoral Castle in time to be at her side before she died.

Prince Charles (now King Charles III) and Princess Anne are believed to have made it to Balmoral Castle in Scotland to say goodbye to their mother. The siblings were already in Scotland, having carried out events in the country earlier in the week including the Braemar Royal Highland Gathering, which they attended together over the weekend.

Charles' wife, Camilla, Duchess of Cornwall, was likely with her husband.

Other members of the royal family rushed to Balmoral on Thursday after news broke that doctors were concerned for the Queen's health but likely did not arrive before she died. The Queen's grandson Prince William, third child Prince Andrew, fourth child Prince Edward and Edward's wife, Sophie, Countess of Wessex, arrived in Scotland later in the day by plane.
