In 2003, Blakemore succeeded Professor Sir George Radda as the head of the Medical Research Council, a national organisation that supports medical science with an annual budget of more than £700 million. The reputation of the Medical Research Council had been damaged by what was perceived as financial mismanagement, the introduction of unpopular funding schemes and a lack of transparency in its dealings with researchers. Blakemore launched a national roadshow to consult the scientific community and quickly changed the mechanisms for handling funds, rationalised the grant schemes, introduced new forms of support for young researchers and overhauled the communications policies of the MRC.
