Brian Hambleton lost his sister Maxine in the Birmingham Pub Bombings in 1974.
He will be protesting tonight outside a lecture delivered by Martin McGuinness, the Deputy First Minister of Northern Ireland.
The lecture is being held at a Peace Centre in Warrington, set up by the parents of a 12-year-old boy killed in an IRA attack.
Mr Hambleton has campaigned ever since the atrocity to bring the killers to justice.
