The Tory Reform Group blog editor said Ed Miliband misrepresented the body when he told prime minister's questions that it did not back coalition plans for the NHS in England.
Ed Miliband claimed "even the Tories don't trust the Tories on the NHS" as he attacked David Cameron over NHS reforms.
But Nik Darlington told Andrew Neil: "Ed Miliband misrepresented the article itself - which I doubt he even read - and he misrepresented the Tory Reform Group's position on health reforms."
He said the publicity over the last 24 hours had highlighted the power of political blogs.
