The parents of IRA bomb victims Tim Parry and Johnathan Ball are preparing for a meeting with Northern Ireland Education Minister Mr Martin McGuinness.
Mr Colin and Wendy Parry and Mr Wilf and Marie Ball will meet the Sinn Féin minister at Warrington, where two bombs killed their sons and injured 56 others in 1993.
The group will have a private meeting at the Tim Parry and Johnathan Ball Young People's Centre, which was opened last year.
After the meeting, Mr McGuinness, the four parents and other families affected by the bomb will attend an advent concert organised to promote peace and build bridges between Ireland and the UK.
Mr Parry (55), says he has mixed feelings about his first-ever meeting Mr McGuinness. He said: "I expect I will have mixed emotions. I totally disapprove of his past but the fact is he is now an elected politician and a prominent individual in the future of Northern Ireland so it is important to meet him.
"I will not go into specific details of what we will be talking about, but we will be covering personal matters as well as political issues.
The advent concert, called "A Bridge To Peace", takes place at Parr Hall in Warrington and features youth choirs from the town and also from Omagh. It was organised by The Bridge, a Warrington-based group which works to forge closer ties to all parts of Ireland.
Tim Parry was 12 and Johnathan Ball was three when they were killed in 1993.
