Same-sex weddings hosted on ships registered in Bermuda will no longer be permitted after the British overseas territory repealed a law on the issue.
Sister cruise lines Cunard and P&O Cruises both have ships registered in Bermuda.
They said they were “very unhappy” about the change in legislation, which will outlaw same-sex marriage ceremonies on their ships.
“We do not underestimate the disappointment this will cause those guests who have planned their weddings,” the companies said in a statement to the BBC.
The lines will instead be offering same-sex couples on-board alternative “commitment” ceremonies.
The Atlantic island, which is home to 60,000 people, legalised marriage between homosexual couples in May 2017, following a Supreme Court ruling.
But a new domestic partnership at approved by Bermuda governor John Rankin on Wednesday, rolls back the legalisation.
