GlaxoSmithKline under fire in China 'bribes' row

GlaxoSmithKline has vowed to review all-third party agency relationships after Chinese police released details of an investigation into bribery allegations.

The British pharmaceuticals company said it was "deeply concerned and disappointed by these serious allegations of fraudulent behaviour and ethical misconduct".

Chinese officers allege GSK has transferred as much as 3bn yuan ($489m; £323m) to travel agencies and consultancies since 2007.
