The home town of a GAA official murdered almost 30 years ago came to a standstill on Friday evening as thousands showed their support for his family’s call for a public inquiry.

It comes after the UK Government confirmed that it will seek to appeal to the Supreme Court over a court ruling that ordered it to hold a public inquiry into the killing of Sean Brown.

Mr Brown’s family met Tánaiste Simon Harris earlier this week as part of their campaign to see a public inquiry heard.

Friday evening saw people travel from across Ireland, including as far away as Co Kerry, to Bellaghy to take part in a Walk For Truth event from St Mary’s Church through the town to the home of Bellaghy Wolfe Tones GAC.

Many wore GAA shirts from their home county as they showed solidarity with the Brown family.

Mr Brown, 61, the then chairman of the club in the Co Londonderry town, was ambushed, kidnapped and murdered by loyalist paramilitaries as he locked the gates of the club in May 1997.

No-one has ever been convicted of his killing.

Preliminary inquest proceedings last year heard that in excess of 25 people had been linked by intelligence to the murder, including several state agents.

It had also been alleged in court that surveillance of a suspect in the murder was temporarily stopped on the evening of the killing, only to resume again the following morning.

Appeal Court judges in Belfast affirmed an earlier High Court ruling compelling the Government to hold a public inquiry.

It said the failure to hold such an inquiry was unlawful.

However, Northern Ireland Secretary Hilary Benn says the case involves a key constitutional principle of who should order public inquiries, the Government or the judiciary.
