Princess Anne will reportedly replace royal renegade Prince Harry as the head of a prestigious navy unit, becoming the first woman to hold the role.
According to The Sunday Times, Princess Anne - the Queen's daughter - will take on the role as captain-general of the Royal Marines. Already the 69-year-old is associated with more than 65 military organisations and is believed to be among the most hard-working royals, attending more than 500 engagements last year.
Princess Anne would become the first woman to hold the prestigious role, which has formerly been held by her father, the Duke of Edinburgh, as well as King George V, King Edward VIII and King George VI.
She would take over from her nephew Harry who is stepping back from the royal family and moving part-time to North America. As part of a deal with the Queen, he agreed to relinquish his military roles.
Prince Harry had been the captain-general since 2017 and will be prevented from wearing his military uniform at public events.
Harry, the Duke of Sussex, and his wife Meghan Markle have been hiding out in Canada since the decision they would step down. They will reportedly return to the UK next month for a set of farewell engagements - including with the Royal Marines.
During his military career, Prince Harry spent 10 years in the army where he undertook two operational tours of Afghanistan and qualified as an Apache helicopter commander. His career came to an end in June 2015.
While working as a royal, Harry founded the Invictus Game - a competition for injured, sick and wounded Armed Forces personnel and veterans.
