Briton Peter Humphrey and wife face trial in GlaxoSmithKline saga
Corporate sleuth and wife now face just one charge over their investigation on behalf of drug giant accused of corruption
British corporate investigator Peter Humphrey and his Chinese-born wife, Yu Yingzeng, will go on trial in Shanghai on July 29.
Authorities detained Humphrey and Yu, a US citizen, last July in connection with the pair's investigations on behalf of GlaxoSmithKline (GSK).
Recent British newspaper reports have linked their detention to a video of former GSK China head Mark Reilly having sex with a woman, as well as the corruption investigation of Britain's largest drug firm.
"We can confirm the existence of the tape," a GSK spokesman said.
Chinese prosecutors originally wanted to charge Humphrey and Yu with several offences, including some relating to illegal business operations.
But they decided to drop all of them except for one of illegally buying information, a source close to the family said.
