BBC finds 'organised prostitution' in some China hotels

A BBC Newsnight investigation has uncovered evidence of organised prostitution inside a number of well known, western-branded hotels in China.
The investigation shows that sex is being bought and sold from third party-run businesses, operating from within some hotel premises.
The Ramada, Intercontinental and Kempinski hotels all deny any knowledge of the practice. Prostitution is illegal in China.
