The sister of an IRA bombing victim has said "the truth has died" with Northern Ireland former deputy first minister Martin McGuinness.
Julie Hambleton said relatives of many of the IRA’s victims were still waiting for "truth and justice", following his death.
She claimed: "He was very opaque and selective with the truth.
With him the truth has died and that's the big problem.
Ms Hambleton, whose older sister Maxine was killed in the 1974 Birmingham pub bombings, offered her condolences to his family.
But she said many relatives of IRA victims were still waiting for answers about what happened to loved ones, including The Disappeared.
She added: "People are piling the praise on him but it isn't valid.
"He didn't come forward with the truth."

Ms Hambleton, who leads the Justice4the21 campaign, which last year won fresh inquests into the deaths of the pub bombings victims, said she still hoped other former IRA members would speak about what happened during The Troubles.
She said: "I can but hope that lips will be looser, not just for our loved ones but for everybody's sake - many of whom still after all these years have nobody to bury."
Former British MP Norman Tebbit said he hopes Mr McGuinness is "parked in a particularly hot and unpleasant corner of hell for the rest of eternity".
Lord Tebbitt, whose wife Margaret was paralysed when the IRA bombed a Brighton hotel during the Conservative Party conference in 1984, said the world is a "sweeter and cleaner" place.
He branded the former IRA commander a "coward" and insisted he had only turned to peace to "save his own skin".
"He knew that the IRA were defeated because British intelligence had penetrated right the way up to the Army Council and that the end was coming.
"He then sought to save his own skin and he knew that it was likely he would be charged before long with several murders which he had personally committed and he decided that the only thing to do was to opt for peace.
"He claimed to be a Roman Catholic.
"I hope that his beliefs turn out to be true and he'll be parked in a particularly hot and unpleasant corner of hell for the rest of eternity."
The 1984 Brighton bombing of the Grand Hotel in the middle of the night killed five and left many injured.
Lord Tebbit said he refused to forgive Mr McGuinness for his terrorist past because "forgiveness requires confession of sins and repentance".
"There was none of that," he added.
Jo Berry, the daughter of Conservative MP Sir Anthony Berry who was killed in the Brighton bombing, said, however, that Mr McGuinness should be remembered for his efforts to build peace.
She said: "Today is a day to really appreciate what (McGuinness) has achieved.
"His legacy is one of reconciliation and peace-building, which is always going to be messy and difficult after a conflict and despite that, he showed us how to move forward and showed us a way where former enemies can work together for the peace of the whole.
What we have now is so much better than what I grew up in. What we have now is peace.
The son of a victim of the Enniskillen bombing said he cannot forgive Mr McGuinness for his terrorist past.
Stephen Gault saw his father Samuel, 49, killed by an IRA bomb in November 1987. The then 18-year-old was also injured in the blast.
The IRA bomb exploded near the town's war memorial during a Remembrance Sunday ceremony, which was being held to commemorate British military war dead.
Eleven people were killed and 63 were injured.
"My feelings are with the Enniskillen families. Martin McGuinness has taken to the grave the truth and the answers that we need to be able to move forward. He knows who bombed Enniskillen. Initially my thoughts and prayers go out to the Enniskillen victims," said Mr Gault.
He added: "I will always remember Martin McGuinness as the terrorist he was. If he had been repentant my thoughts might have been slightly different.
"But he took to his grave proud that he served in the IRA. There was no remorse or repentance from him even up to his death."
Mr Gault said he feared that Mr McGuinness would only be remembered as a peacemaker.
"My fear is Martin McGuinness is going to be remembered as this great peacemaker similar to the way Nelson Mandela was remembered after his death. My fear is that his horrific past will not be mentioned.
"People might say I am unchristian that I have no sympathy for his family. But it wasn't Christian to send people out to murder innocent people.
"Did the McGuinness family feel any sympathy for the Gault family when my father was cruelly and brutally murdered at the age of 49 by an IRA bomb?
"I have heard all this talk about how Martin McGuinness was only 66. My father was only 49 when he was murdered. He wasn't even 50. He was a very young man."
DUP Deputy Leader Nigel Dodds said Mr McGuinness contributed to the hurt and suffering in Northern Ireland, but also to building peace.
He said the complexities of his life reflected the complexities of 40 years in Northern Ireland history.
Speaking on RTÉ's Today's with Sean O'Rourke, Mr Dodds said many victims will feel sore at the eulogies being paid to Mr McGuinness, but we must pay tribute to the fact that he moved Northern Ireland on.
"Victims will no doubt be feeling very sore at the eulogies being paid to him. They will remember the hurt and suffering and pain that he brought to them, and visited upon their families at the early part of the Troubles.
"At the same time we must remember and pay tribute to the fact that he moved Northern Ireland forward."
