Victims' families are travelling to Westminster today to protest against the British government's Troubles amnesty.
Demonstrations are also taking place in Derry and Belfast, as the proposal is debated in the House of Commons.
It would ban prosecutions for those who co-operate with a panel that investigates Troubles' killings.
John Teggart's father, Danny, was murdered in the Ballymurphy massacre in 1971 - he says the plan should be scrapped.
"That's actually the worst proposal that any government has ever come up with for dealing with our past.
"It's absolutely disgraceful, and our shock throughout the whole victim sector of how blatant this proposal is, for a total amnesty for those involved in murdering our loved ones."
