The brother of a woman killed in the Birmingham pub bombs in 1974 said he is outraged that Martin McGuinness is to deliver a peace lecture in Warrington on Wednesday.
Brian Hambleton, whose sister Maxine was 18 when she was murdered in the bombings, said inviting the former IRA man to speak on the issue of peace is “like inviting Myra Hindley to a childminding conference”.
Mr Hambleton will picket the event with other members of the Justice for the 21 group.
The deputy First Minister was invited to speak in Warrington by Colin Parry, a father of a 12 year-old boy killed in an IRA bomb attack in the town 20 years ago.
Mr Hambleton, 58, told the Birmingham Mail: “It’s like inviting Myra Hindley to a childminding conference.
“It is wrong. That man has no right to talk about peace and resolution. I cannot believe he is being given a red carpet to a stage in mainland Britain.
“My sister was not born to be killed by a bomb. I will never give up. I could be shot for doing this, but I don’t care.”
The IRA, although widely believed to be responsible for the Birmingham bombings, has always denied being responsible.
