On Tuesday 3 February, MPs approved the creation of IVF babies using DNA from three different people in order to prevent inherited diseases.

This means the UK is now set to be the first country in the world to permit the treatment - despite calls from critics who believe it crosses an unacceptable ethical line.

If the House of Lords ratifies the move we could see the first baby conceived through the procedure next year.

But are there any family law issues to be considered? What about the third person's DNA that is used? Would they have any access rights to the child?

Whatever legal uncertainties there may be - or your ethical stance on the issue - it is clear that the UK remains at the forefront of medical and scientific innovation.
