Exactly 25 years ago today, the Provisional IRA planted two bombs in Warrington, killing two young boys and injuring more than 50 people in a busy shopping area. The attack claimed the lives of 3-year-old Johnathan Ball and Tim Parry, who was 12. The youngest survivor was just 13 days old. Her pram was metres from the bin where the second bomb exploded. Today, in a rare television interview, Harriet Vickers, now 25, has been talking to Jane Deith about the day that changed her life forever.
