SINN Fein have claimed Gerry Adams' participation in a minute's silence for female murder victims is "appropriate", despite his questioning earlier this year by police investigating the murder Jean McConville.
Mr Adams stood outside holding a pair of women's shoes that represented one of 78 women murdered by their partners of ex-partners since 1996.
He joined other TDs in the event organised by Women's Aid.
The commemorative demonstration comes seven months after Mr Adams was arrested and spent four days being questioned by PSNI officers investigating Ms McConville's abduction and murder by the IRA in 1972.
He held a press conference after his release and insisted he is innocent of any involvement in the sickening killing.
Sinn Fein last night defended Mr Adams' participation in yesterday's event.
"Yes, I do think it is appropriate that Gerry took part in that," a party spokesman said.
"Gerry has always said he had no hand, act or part in the killing of Jean McConville," he added.
Yesterday's somber memorial also remembered ten children murdered alongside their mothers.
The minute's silence was held ahead of International Day Opposing Violence Against Women and the start of the Women's Aid One in Five Women National Awareness Campaign next week.
Margaret Martin, of Women's Aid, said current or former partners have carried out more than half of all solved female homicides.
"With one in every two women murdered being killed by a current or former boyfriend, partner or husband, it is imperative that we act now before more lives are stolen," she said.
Memoriam cards remembering the 78 women have been distributed to politicians, media, domestic and sexual violence services and other organisations nationwide.
"Domestic abuse is a hidden and misunderstood issue in Irish society," Ms Martin said.
"One in five women in Ireland experiences domestic violence including physical, emotional, sexual and financial abuse," she added.
