In an interview with the Daily Mail, Mountbatten said the wedding would be held in a private chapel on his estate in Devon. While the members of the core royal family — meaning Queen Elizabeth II and her direct descendants — are not expected to attend, the couple has the full support of the royal family, Mountbatten told the Mail.
Mountbatten, a third cousin of Queen Elizabeth II and descendant of Queen Victoria, became the first royal to publicly identify as gay in 2016. He has three children with his former wife, Penny Mountbatten, who has been openly supportive of her husband’s relationship with Coyle. She said last week that she plans to walk Mountbatten down the aisle at the suggestion of their daughters.
While Mountbatten will go down in history books as the first member of the extended royal family to marry a member of the same sex, news of his marriage isn’t raising eyebrows in Britain. According to data collected by the British national census in 2016, more than 60 percent of Britons do not find anything wrong with same-sex relationships. Same-sex marriage was legalized in most parts of the country four years ago, and while it is still not recognized in Northern Ireland, civil partnerships have been available since 2005.
Mountbatten is also sufficiently distant from the throne that his marriage does not raise any issues involving the constitution, said Jonathan Thomas, the publisher of Anglotopia.net, who has been covering the British monarchy and British culture since 2007.
The royal family still abides by the rules of a law passed in 1772, titled the Royal Marriages Act, that requires the first six people in the line of succession to receive permission from the ruling monarch before they marry. (The queen gave her formal consent to Prince Harry and Markle in March.) Because Mountbatten is not in the line of succession and because he already has children, his marriage to Coyle has little bearing on the leaders of the family.
Nonetheless, Mountbatten has broken new ground, Thomas said. “Change happens a lot around the edges, and as people further from the center make changes, these will increase toward the center,” he said.
