The Chinese government has said it has "no information"
about the death of British businessman Neil Heywood which has been
linked to a political scandal engulfing the Communist Party.
Mr Heywood was found dead in a hotel room in the southern city of Chongqing last November.
Chinese police said he died of "excessive alcohol consumption".
His body was then cremated without an autopsy being performed.
But the British Embassy in Beijing has now asked the Chinese
government to investigate after being made aware of "suspicions and
rumours surrounding the death".
Sources have told Sky News that Mr Heywood was not a heavy drinker,
was in good health, and was just 41 at the time of his death.
Mr Heywood
had lived in China since the late 1990s, was married to a local woman
with whom he had two children, and worked as a non-executive director
for a Chinese Aston Martin dealer.
He also consulted for a strategic intelligence company that was founded by former MI6 officers.
Mr Heywood told several of his acquaintances that he enjoyed a close
relationship with the family of Bo Xilai, a top Communist official who
is now at the centre of a sensational political scandal.
We are aware of suspicions and rumours surrounding his
death. After we were made aware of these suspicions we passed them on to
the Chinese authorities and asked them to investigate further

Mr Bo was sacked as Chongqing's Communist party chief earlier this
month after his former police chief, Wang Lijun, sought refuge inside a
US consulate.
It is thought he asked for political asylum and gave American diplomats evidence implicating Bo Xilai in criminal wrongdoing.
Mr Wang eventually left the consulate after a 24-hour standoff, during which Chinese police blocked off surrounding streets.
He is now being investigated by the Communist Party, while Bo Xilai's whereabouts are unknown.
The case has electrified Chinese websites, where speculation runs
rife that Mr Bo had been plotting a coup against leaders in Beijing.
There are other claims that his downfall was fuelled by the lavish
lifestyle of his son, Bo Guagua, who was educated at Harrow and Oxford.
However new reports suggest that Mr Bo fell out with his chief of
police after he raised suspicions that Mr Heywood may have been
poisoned.
It is also claimed Mr Bo's wife may have been involved in a business dispute with Mr Heywood.
There is speculation on Chinese internet sites that both Mr Bo and
his wife are now under house arrest, though this has not been confirmed
by the Chinese authorities.
Asked whether Mr Heywood's death was connected with Mr Bo's downfall,
a Chinese foreign ministry spokesman said he had "no information on the
matter".
He also declined to confirm whether or not the Chinese government had been asked to investigate the death by the UK Government.
