By Simon Tomlinson PUBLISHED: 11:56 EST, 17 April 2012 | UPDATED: 13:32 EST, 17 April 2012 David Cameron today demanded assurances from China over the investigation into the death of Neil Heywood as pictures emerged of the hotel where the British businessman met his murky end. Mr Heywood, 41, was found dead in mysterious circumstances at the Nanshan Lijing Holiday Hotel in Chongqing last November. It is one of the city's most secluded areas, but one which has now attracted the unwanted attention of the world as speculation over the ex-Harrovian's demise intensifies. Suspicious: The reception area of the Nanshan Lijing Holiday Hotel in Chongqing, China, where British businessman Neil Heywood was found dead, apparently poisoned after threatening to expose the corrupt dealings of the wife of Communist Party chief Bo Xilai
