MPs made history today by voting to legalise a new fertilisation technique that creates so called 'three-parent babies'.
The technique allows genetic material donated by a third person to be used to eliminate life-threatening conditions in new babies.
If the amendment passes the House of Lords, Britain would be the first country in the world to allow the ground-breaking technique.
ITV News' Health Editor Rachel Younger reports:
MPs have voted in favour of a ground-breaking but controversial technique that could see IVF babies conceived with DNA from three people.
A vote on three-parent babies, taking place today, could determine paediatric nurse Rachel Steel's chances of having her own healthy kids.
The parents of a baby with a life-limiting disorder say their future happiness will be decided by today's three-parent family vote.
