One year ago, Jack Merritt and Saskia Jones were senselessly killed in London as they volunteered at a conference on criminal rehabilitation. 

Their murderer, Usman Khan, was a convicted terrorist who'd been released from prison just a year earlier.

On this edition of the Sky News Daily podcast we remember the victims and heroes of the 2019 London Bridge terror attack, and hear from Rosca - an ex-gang member and now rapper - who says Jack Merritt saved him from a life of crime.

Plus Sky's Diana Magnay walks us through what it was like to be reporting on the day that Jack and Saskia's lives were taken and we hear from Nick Aldworth, the former counter-terrorism national co-ordinator, about whether the UK's de-radicalisation programmes are really working.
