Although Sally Davies, the UK's Chief Medical Officer (CMO), had described homeopathy as "rubbish", it was reported in May 2014 that health secretary Jeremy Hunt, at Tredinnick's urging, had requested a review of three studies by the French company, Boiron. These were found not to demonstrate the effectiveness of homeopathy, and the quality of the research in them was later questioned by Edzard Ernst. Tredinnick told "The Independent" in June 2015 that homeopathy's common rejection was the result of "vested interests trying to protect their own turf".
