Making stuff up for political gain?

Someone at the Grapevine posted a link to this story, which is about twins seperated at birth who fell in love and got married. Very soap operaesque and a real sob story. I know, I scoff but while I felt awful for these people when I read the story, although I had questions, the more I thought about it more it seemed the story is too fantastic to be true. And yes, I am well aware that fantastic things happen every day so let's take a look at the "facts."

Twins who were separated at birth and adopted by different sets of parents later married each other without realising they were brother and sister, a peer has told the House of Lords.

And

Alton raised the case of the married twins -- who were born after IVF treatment -- during a debate on December 10, details of which only appeared on Friday.

When I read this I thought, the hell? Where did they come from? A baby farm? Who has in vitro fertilization, test tube babies, then gives the babies up for adoption, especially to two completely different sets of parents?

Parents who then later don't start worrying when their children fall in love with another adopted child who happens to have the very same birthday.

And the children supposedly found out after they were married. How did they find out? Mum or Dad finally spoke up? They had DNA testing and surprise, they were twins?

Why are there no names or details given?

Further reading show this interesting tidbit:

The Catholic politician -- who discovered the case after talking to a judge -- used it to highlight perceived deficiencies in the government's proposed Human Embryology and Tissues Bill, which is currently going through parliament.

So what we essentially have here is a FOAF, a friend of a friend, the classic sign that a story is really an urban legend. And this politician is using the story to argue against a bill he doesn't like, and not just a bill he doesn't like but:

The bill is designed to make it easier for lesbian and gay couples to have children through assisted reproduction, recognising same-sex partners as legal parents of babies conceived through donated sperm, eggs or embryos.

Isn't this incredible, unverified story amazingly convenient for him?
