The UK has become the first country in the world to legalise the creation of in-vitro fertilisation (IVF) babies using DNA from three people after peers overwhelmingly backed the proposals.

A vote to approve a controversial IVF technique to allow three-parent babies will offer "real hope" to families affected by certain genetic disorders, supporters have claimed.
Speaking as the House of Lords voted against an amendment which would delay the new laws, Lord Howe said it would have been "cruel and perverse" to hold the technology back.

The new regulations mean healthy mitochondria can be extracted from a donor, and implanted to replace any damaged or unhealthy mitochondria in a woman's egg.
Critics had said the risks of the procedure were not yet fully known, and voiced concern that the legislation was being pushed through too hastily.
