Manchester Arena bombing: the inside story of the terror attack that shook Britain

The Manchester Arena bombing was the deadliest terror attack in Britain in a decade. Salman Abedi killed 22 people - including children and teenagers - when he detonated a bomb at an Ariana Grande concert in May 2017. But how was he able to do it? And how was his brother finally brought to justice years later?

Neil was a senior counter-terrorism figure at the time. He reveals how the security services responded, where the intelligence failures were, and the painstaking effort to prosecute Hashem Abedi for his role in the plot.

Andy had spent months in Manchester before the attack, investigating a different terror cell, and explains how so many members of a community on one Moss Side estate became radicalised by ISIS.

Plus, they both explain how the tragedy led to Martyn's Law, and whether what we learned from this attack is enough to prevent the next one.
