The documentary showing what life is like for those who work at MI5 was first shown on Thursday 27 February on ITV1. Over the course of three months, a small team at ITV were given controlled access to our headquarters at Thames House to provide an insight into the people who work behind the scenes to keep the country safe.
The staff members, who have their identities protected, describe what they do, how they do it, and what it feels like to work for MI5.
Speaking to ITV News, Director General Sir Andrew Parker explained why he had ageed to allow cameras into our otherwise secret organisation:
"MI5 exists to serve and protect the public and this country, so where it's possible for us to explain a bit more about ourselves, we'd like to do that. I think it's helpful if the public can see a bit more about what we're like as people, and the human side of MI5".
'Inside MI5: Keeping the UK safe' is available to view on ITV Hub. You can watch clips from the programme here:
