Thousands of people have attended a rally in support of the family of murdered GAA official Sean Brown.
His 87-year-old widow Bridie and children are demanding a public inquiry into the circumstances of his killing.
The crowd from clubs all over the country walked behind the Brown family from the church in the village of Bellaghy, Co Derry to the GAA grounds that are named in his memory.
Mr Brown's daughter, Clare Loughran, thanked the large crowd.
"We're absolutely overwhelmed. We can't believe that the crowd that have come here tonight, the fantastic array of colours that have come.
"People, are supporting us from every corner of Ireland and even further afield.
"And it really sends a very strong message to the Secretary of State and the Northern Ireland office to say, Look, this community backed Sean Brown, this community backs the truth."
GAA President Jarlath Burns also attended. He said he felt a "defiance" in the crowd attending tonight's protest.
He said the Association was not going to let the Brown family be treated in the way they had been any longer.
Sinn Féin President Mary Lou McDonald attended, as did Stormont First Minister Michelle O'Neill.
Senior SDLP MLAs Patsy McGlone and Justin McNulty were also in the crowd.
Sean Brown was abducted in 1997 by loyalists as he was locking up Bellaghy Wolfe Tones club of which he was chairman.
He was driven away and shot.
The family have mounted a lengthy legal campaign to establish why he was targeted.
It emerged during legal discovery that 25 people had been linked by intelligence to his murder, several of whom were working as state agents.
Northern Ireland's Appeal Court recently affirmed a legal order forcing the Northern Secretary Hillary Benn to convene a public inquiry into the murder.
The courts have said it is the only legal mechanism currently available that can deliver a proper human-rights compliant investigation.
Other legal avenues have been shut down by the British goverment’s controversial new legacy arrangements.
The Brown family say they have no confidence in the new structures and their ability to deliver the full facts of their father’s murder.
The UK government has said it is appealing the decision ordering it to hold a public inquiry to the Supreme Court in London.
The family has urged the British government to abandon the legal challenge and convene the inquiry.
They are being supported by the Irish Government.
