The secrets of undercover policing

You've seen it in the movies, but what does undercover policing really involve? What makes an effective covert officer, and just how brutal is it for the men and women who are brave enough to go incognito? And do you get paid more for crossing the thin blue line and infiltrating the very people you're trying to convict?

In this episode, Andy and Neil explain the realities of undercover policing, with Neil drawing on his vast experience of deploying covert units throughout his career, and answering the key questions about what he describes as 'one of the most difficult jobs in policing'. They also speak to James Bannon, a former Met officer who went undercover in the 1980s with Millwall's notorious football firm - and whose story was later turned into the cult film, 'I.D'.

Later, Andy speaks to Alice Levine about her new podcast 'Explosive Lies' - part of Global's 'Unmissables' series.
