Shamima Begum was 15 years old when she left Bethnal Green with her two school friends to travel to Syria to join the ISIS Caliphate in 2015. From day one, ITV News, led by its Global Security Editor Rohit Kachroo, has followed the story of Shamima closer than anyone else.

With unparalleled archive, unique testimonies, exclusive interviews and analysis from an award winning journalist, we unpack the story from when it started, to where we are now.

It's a story with one individual at the heart of it, but one that involves multiple agencies, institutions and countries, all seeking to shift the blame for how and why this happened.

In Shamima Begum - The Blame Game, Rohit Kachroo addresses those questions.
