Wendy Parry, whose 12-year-old son Tim was killed alongside three-year-old Johnathan Ball in the Warrington bombing on March 20, 1993, will receive an OBE in the Queen's Birthday Honours.
A further 56 people were injured by two bombs put in litter bins the day before Mothering Sunday. No warning was given and nobody has ever been prosecuted for the outrage.
Mrs Parry, who set up the Tim Parry Johnathan Ball Foundation for Peace with husband Colin, is awarded the OBE in the year that marks the 20th anniversary of the attack.
