The UK is now set to become the first country to introduce laws to allow the creation of babies from three people.

In a free vote in the Commons, 382 MPs were in favour and 128 against the technique that stops genetic diseases being passed from mother to child.

Mitochondria are the tiny compartments inside nearly every cell of the body that convert food into useable energy. They have their own DNA which does not affect characteristics such as appearance.

Defective mitochondria, which are passed down only from the mother, lead to brain damage, muscle wasting, heart failure and blindness.

The technique uses a modified version of IVF to combine the DNA of the two parents with the healthy mitochondria of a donor woman.

It results in babies with 0.1% of their DNA from the second woman and is a permanent change that would be passed down through the generations.

Other groups, including Human Genetics Alert, say the move would open the door to further genetic modification of children in the future - so-called designer babies, genetically modified for beauty, intelligence or to be free of disease.

David King, from the campaign group, said: "Once you cross the ethical line, it is very hard not to take the next step of designer babies."
