LONDON/BEIJING (Reuters) - Britain has asked China to investigate the death of a British man in the southwest Chinese city of Chongqing formerly run by Bo Xilai, the leadership contender whose abrupt ousting shook the ruling Communist Party.
The British national, Nick Heywood, died and was cremated in November. Questions about his death have been posted on Chinese microblogs, which have linked it to the background to Bo's ouster.
"We have recently asked the Chinese authorities to investigate the case further after suggestions that there were suspicious circumstances involved in his death," said a spokesman for Britain's Foreign Office.
He said the office was "aware of rumors and speculation related to the case" but did not necessarily give them credence.
A spokesman for the British embassy in Beijing said Britain had been told Heywood had died from over-consumption of alcohol and been cremated in Chongqing in November.
Bo was sacked as Communist Party secretary for Chongqing after his former police chief, Wang Lijun, took refuge inside the U.S. consulate in nearby Chengdu for a day on February 6. He was persuaded to leave by Chinese officials who then took him away for investigation.
Wang's flight triggered a torrent of speculation about Bo, a charismatic contender for a top post in the central leadership later this year. He had sacked Wang as police chief shortly before he fled to the U.S. consulate.
Earlier this week, two Chinese ex-officials told Reuters central leaders had circulated an account of tension between Bo and Wang. The Wall Street Journal cited people it said were familiar with the case as saying Wang said he had fallen out with Bo after telling him he believed Heywood was poisoned. Heywood's body was cremated without an autopsy, it said.
The paper cited unnamed diplomats and other people it said were familiar with the matter saying Wang presented documentary evidence against Bo at the U.S. consulate but it rejected him because U.S. officials feared accepting him would severely damage relations with China.
At a news briefing days before his ouster, Bo suggested that people spreading baseless accusations were serving the agenda of crime bosses that he fought in Chongqing.
Neither Bo nor his wife could be reached for immediate comment. They have not appeared in public since Bo's ousting.
The Chongquing government office and Chinese Foreign Ministry spokesman's office in Beijing were unavailable for comment about the British request.
The Financial Times reported that Heywood, a former pupil of Harrow School, a prestigious private British boarding school where Bo's son Bo Guagua later studied, had good connections to the Bo family and was married to a Chinese national. He had worked in Beijing as a consultant for a number of companies.
In London, a spokesman for Hakluyt, a UK-based private business consultancy founded by former British intelligence officers, said that it was one of several companies which occasionally received advice on China from Heywood.
A Hakluyt spokesman told Reuters that Heywood "had a long history advising companies on China and we were among those who sought his advice. We are greatly saddened by his death."
