The Taoiseach has said that the Government would support a public inquiry into the death of Sean Brown.
"It is something we support and it is something we will engage with, with the British government," Micheál Martin said on his way into a Cabinet meeting.
Mr Brown was chairman of Bellaghy Wolfe Tones GAA in south Derry and was locking up the gates of the club when he was assaulted, abducted and murdered by a loyalist gang in May 1997.
The 61-year-old father of six was taken to a remote country lane outside Randalstown and shot six times.
Yesterday, Mr Brown's family met Tánaiste Simon Harris at Government Buildings about their ongoing campaign for a public inquiry into the murder.
The family described the meeting as "very positive".
Speaking to reporters, the Taoiseach said the Government is supportive of Mr Brown's family as he referred to the difficult trauma they have endured for so long.
He said they will be raising it with the British government along with other issues pertaining to legacy.
Mr Martin said a lot of progress has been made in the last year on legacy issues.
He said before the Labour Party came into office in the UK, the situation in terms of legacy matters was "fairly grim".
He said that that has changed considerably and there is continual engagement with the British government on this.
The Tánaiste said he met Bridie Brown, Mr Brown's 87-year-old widow, last night on the 28th anniversary of her husband's "brutal murder".
He said he remains committed to articulate in every forum "the need for answers for the Brown family and the need for that human rights compliant inquiry".
Meanwhile, Siobhan Loughran, Mr Brown's daughter, has said that she believes the Tánaiste will provide support for a public enquiry into her father's murder.
"We will take this as far as we possibly can and are calling on the Irish government to put as much pressure as they can on the British government," she said, "because we will continue this fight to get what we greatly deserve".
Speaking on RTÉ's Morning Ireland, she said Mr Harris said that her family has waited too long and there must be a full and open inquiry.
Ms Loughran said that they presented Mr Harris with a lot of information at yesterday's meeting, outlining all the issues the family has encountered since "the very first day".
She said that her mother wants to know why her husband was murdered.
"She's now 87," Ms Loughran said, "and this is very hard on her".
