I could never forgive McGuinness, says Father of Warrington bomb victim

The father of a schoolboy killed in the IRA's Warrington bomb has said though he could never forgive Martin McGuinness he believes he was sincere about making peace.

Colin Parry invited Mr McGuinness to deliver a high profile lecture in the town in 2013 - 20 years on from the attack that killed his son Tim and another boy Johnathan Ball.
