Secretary of State Chris Heaton-Harris has said that no one has an alternative to the legacy bill

The UK Government's Troubles (Legacy and Reconciliation) Bill includes a form of limited immunity for some perpetrators of crimes committed during the conflict, if they collaborate with a truth recovery body.

It would also prevent future civil cases and inquests into Troubles offences.

The legislation is opposed by all major Stormont parties, the Irish Government and victims' campaign groups.

Chris Heaton-Harris's comments on the bill came as he spoke to media after announcing a peace funding project for Northern Ireland, in collaboration with the EU and Republic of Ireland, totalling close to £1 billion.

There was a silent protest held against the Legacy Bill outside the Newforge Sports Centre in south Belfast, where the Secretary of State met with Irish premier Leo Varadkar and vice-president of the European Commission Maros Sefcovic to announce the new funding scheme.

Mr Heaton-Harris said despite the widespread opposition to the Legacy Bill from politicians and victims, he has not been presented with an alternative option.

"Lots of people ranged against the Legacy Bill, but no-one has an alternative for what could possibly replace it, and no-one can tell me that the current situation that has been running for the last 25 years has been satisfactory to the families of victims either," he said.

"So I fully acknowledge this is not perfect. I've met with an awful lot of people who lost loved ones in the Troubles, I've met with people who had family members maimed, I've met with people who are truly victims, I cannot put myself in their shoes.

"But 25 years on, some of these families will have been looking for answers (from) when the Troubles commenced - you could say the best part of 40 or 50 years - and haven't really received them.

"This is an honest and true attempt to try and get information for those families."

Mr Varadkar said he has urged Mr Heaton-Harris to pause the UK Government's controversial bill to deal with the legacy of the Northern Ireland Troubles.

"I had a chance to meet with the Secretary of State today and once again expressed the Irish Government's opposition to the Legacy Bill," he said.

"It isn't law yet, it still has to pass through the House of Lords and receive Royal Assent. Once again, I appealed to the UK Government to pause this, we don't think it is the right thing to do."

Mr Varadkar has previously said he would "give consideration to whether an interstate case is appropriate" in the case of the Legacy Bill.

States can lodge legal applications against each other in the European Court of Human Rights under article 33 of the ECHR.

Ireland has previously taken an interstate case against the UK in relation to interrogation techniques used in Northern Ireland from 1971 to 1975.

In Belfast yesterday, Mr Varadkar said he would be seeking legal advice on whether the Irish Government would take such a case against the UK.

"We haven't yet made a decision on whether or not we will take an interstate case," he said. "That is a big decision, it is not a small thing to do to take a neighbouring state to court."
