It's 20 years ago this week since the death of 3 year old Jonathan Ball and 12 year old Tim Parry in the Warrington Bombings.
There were those who called for revenge and retaliation against those responsible and their supporters. But one family has led a single-minded fight for peace and reconciliation ever since.
Colin Parry had to switch off his son Tim's life support machine in the days after the attack. We went with him to the Northern Ireland Assembly to meet political leaders, some of whom openly supported the IRA back in 1993.
