In an exclusive investigation, The Times and The Sunday Times have revealed that a Tory parliamentary researcher arrested on suspicion of spying for China was the director of an influential policy group on Beijing. Chris Cash says he is “completely innocent”, and that claims that he spied for China are “extravagant” and “against everything I stand for”.

Now, for the first time, the Sunday Times journalist who broke the story of Cash's arrest gives her behind-the-scenes account of how the investigation unfolded – and why we're choosing to name the suspected spy.
