The story of two twins parted-at-birth, then meet later in life, marry without realising they’re twins and then getting the marriage annulled in the courts has done the rounds of all the papers it was even reported on Radio 4′s today program. I thought at the time it had to be absolute rubbish. And John Henley of The Guardian agrees with me.

Here’s the thing: it all came from a single remark more than a month ago by the vehemently anti-abortion Roman Catholic peer and father of four, Lord Alton, in favour of all children having the right to know the identity of their biological parents. He had heard about this particular case, he said, from the judge who handled the annulment. Or perhaps (he later admitted) a judge who was “familiar with the case”. Britain’s top family judge, Sir Mark Potter, has never heard of the story.

The whole thing is completely unlikely – think about it.
