Norfolk MP George Freeman has stood down as the prime minister's life science advisor, saying it is up to ministers to implement his work on medical research and agriculture.

The Mid-Norfolk MP, who was working in the voluntary role helping the government, said he wanted to step back and make sure Norfolk benefits from the opportunities in the sectors.

He has spent two-and-a-half years doing the role for the government, but was overlooked in David Cameron's recent reshuffle of ministerial roles.

Mr Freeman had a 15-year career in biomedical venture capital, much of it spent around the Cambridge cluster area, before winning the Mid-Norfolk seat in 2010.

He said: 'After two and a half years working in a voluntary role helping government launch Industrial Strategies for the UK's Medical and Agricultural sectors, with significant opportunities for our area, I have decided to step back to concentrate on helping ensure Norfolk benefits, and on the key campaigns I'm running locally on the A47, broadband, rail, skills and healthcare. Having come to Parliament after a career helping start innovative small businesses in the medical and agricultutal sectors in our region, it has been a privilege and pleasure to champion and promote the potential of our area as a hub of innovation, and secure major new investment for Norfolk.

'These industrial strategies have been recognised internationally and it is now for ministers and depts to implement them.

'I look forward to continuing to help our councils, universities and local businesses create the jobs and opportunities our school leavers need and deserve, and promote Norfolk's education and skills to attract the investment we need.'
