David Cameron handed Freeman the role as part of an expansion of the UK’s global trade and inward investment mission spearheaded by United Kingdom Trade & Investment.
He is also chair of the All-Party Parliamentary Group on Science and Technology in Agriculture.
Appointed government adviser on life sciences in 2011, he has been closely involved in the launch of the UK’s industrial strategies for agri-tech and life sciences, with major investment in the eastern region.
Last year he co-founded the Norwich-Cambridge Research Partnership with Lord Sainsbury and Norfolk and Cambridge County Councils, and he has been campaigning for a major upgrade of the Norwich-Cambridge Railway.
Freeman said the unpaid role was a great opportunity to “support and champion the world-class potential” of local businesses in the east of England.
“After recent decades of unsustainable growth based on booms in debt, public spending and the City, we need, and the government is right to be pursuing, a long term recovery based on the UK selling things the fastest growing markets of the world need,” he added.
