Fletcher said there were already exemptions for community benefit societies, formerly known as industrial and provident societies, and he wanted to extend these to all third sector organisations.
"I think there's a chance of getting this into law now," he said. "There's a real window of opportunity. The reform of the Financial Services Authority is already under way, there's big interest from government in social investment and there's a drive to reduce red tape for the sector."
The Cabinet Office has expressed support for the idea of a new regulatory framework in its strategy paper Growing the Social Investment Market, in which it said it would "seek further evidence on the impact of the regulatory framework on social and community investment to assess whether it is proportionate".
One of the six key recommendations in Lord Hodgson's report on red tape in the third sector, Unshackling Good Neighbours, was the creation of a class of "social investors" who could invest under less strict guidelines because they understood they were receiving both a social and financial return.
