How the former Prince Andrew could be removed from Britain's line of succession

Experts say the process of removing him from the line of succession could be lengthy because it requires the involvement of about a dozen countries that also call the British monarch their head of state.

Nonetheless, momentum for change appears to be building after police last week arrested Mountbatten-Windsor on suspicion of misconduct in public office. Following the release of millions of pages of files last month related to Epstein by the U.S. Justice Department, the former prince was accused of sharing confidential trade information with the disgraced financier when he served as U.K. trade envoy from 2001 to 2011.

Mountbatten-Windsor, 66, was released without charge on Thursday after spending about 11 hours in custody, but he remains under investigation.

“The government is clear that we are not ruling out action in respect of the line of succession at this stage, and we will consider whether any further steps are required in due course," Darren Jones, Prime Minister Keir Starmer's chief secretary, told lawmakers on Monday.

Any such measure will only take place once the police investigation is finished, he added.

An act of Parliament is required

Under the current line of royal succession, Charles' son Prince William is heir to the throne and his three children — Prince George, Princess Charlotte and Prince Louis — are next. Prince Harry is fifth, while his two children, Prince Archie and Princess Lilibet, are sixth and seventh in line.

Mountbatten-Windsor — who was second in line to the throne at his birth — currently follows them in eighth position. His daughters, Princesses Beatrice and Eugenie, are at ninth and 12th places respectively.

Removing him from the line of succession would require an act of Parliament, which needs lawmakers' approval.

One party, the Liberal Democrats, has been vocal about supporting such a move.

"I think it would be intolerable for Andrew Mountbatten-Windsor to succeed to the crown," party leader Ed Davey said last week. “It’s not as remote as some people think."

Beyond Britain

Any change to the line of succession would also require backing from about a dozen Commonwealth countries where Charles is head of state.

Australia’s Prime Minister Anthony Albanese said Monday he would back any U.K. government plan to exclude Mountbatten-Windsor.

“These are grave allegations and Australians take them seriously,” he wrote in a letter to Starmer. “I agree with His Majesty that the law must now take its full course and there must be a full, fair and proper investigation.”

Starmer’s government is not believed to have received similar letters from 13 other countries that also have Charles as head of state, including Canada, New Zealand, Jamaica, the Bahamas and Tuvalu.

Robert Hazell, a politics professor who founded the Constitution Unit at University College London, said in some countries it requires a formal constitutional amendment, while in others it can be done by legislation. He expressed doubt that the U.K. or the other governments would want to spend time removing Mountbatten-Windsor from the succession line given he is only eighth in line.

“The last time this happened was for the Succession to the Crown Act 2013, which made the law of royal succession gender neutral,” he said. “It took two years of protracted negotiations for all the different countries to amend their own laws or constitutions.”

The status of Andrew’s daughters

One question is whether excluding Mountbatten-Windsor would affect his daughters, who are not working royals, and their children.

“Not necessarily — it depends how the legislation is framed,” Hazell said.

The last time a royal was removed from the line of succession was after King Edward VIII abdicated in December 1936 to marry American divorcee Wallis Simpson. At the time, the law was changed to strike him and any descendants from the list.

For his part, Charles has not publicly indicated whether he would support or oppose removing his brother from the line of succession. The monarch stressed that the law must take its course in the investigation, adding: “My family and I will continue in our duty and service to you all.’’

Reports in the British media, however, suggest the palace is not against a legal change to remove Mountbatten-Windsor from the line of succession. Citing an unnamed palace source, the Times of London reported on Saturday that the royal family said it would “never get in the way” of what Parliament decides.
