LONDON, England (CNN) -- British twins who had been separated at birth learned they were related only after they had become husband and wife, a senior British lawmaker said. The marriage has been annulled.
The couple's identities have been protected for legal reasons.
Their case was first highlighted by Lord Alton of Liverpool during a discussion on donor conception in the House of Lords in December, but only came to light Friday.
The peer told the House of Lords that a court annulled the union as soon as the twins' true relationship became known.
"They were never told that they were twins," he said during the Dec. 10 debate on a law covering human fertility and embryology. They had been adopted by separate families and "met later in life and felt an inevitable attraction, and the judge had to deal with the consequences of the marriage that they entered into and all the issues of their separation."
No further details about the couple have emerged, and it is not known when the marriage took place or how long they were together before they discovered the truth.
The RestI have it on authority that their first names are actually Caligula and Drusilla...
You'd think that that would be a clue that you're marrying your sibling.
