Plans for a £10 million scientific research centre to be based on the site of the Olympic drug testing labs have been announced by David Cameron.

The centre in Harlow, Essex will be home to the world's first phenome centre, allowing experts to learn more about physical characteristics like hair and eye colour.

It will also be used to better investigate diseases including diabetes and dementia and for the development of new treatments and drugs.

At the moment the facility is home to the 2012 Games' anti-doping centre where scientists analyse samples from all of the medalists.

The new centre will be funded over five years from the Medical Research Council and the Department of Health's National Institute for Health Research and will be run by drugs giant GlaxoSmithKline.
