The act was the government's controversial attempt to "draw a line" under the Troubles in Northern Ireland.

It was first proposed by the then prime minister Boris Johnson in 2021 as a solution to ending what he called "vexatious prosecutions" of former soldiers.

It was passed in 2023, but was opposed by victims' groups and all the main political parties in Northern Ireland.

The act created a new legacy body known as the Independent Commission for Reconciliation and Information Recovery (ICRIR) to take over all Troubles-era cases from 1 May 2024, including those on the desk of the Police Service of Northern Ireland (PSNI).

It also shut down all historical inquests.

The act's most controversial element, the offer of conditional immunity to suspects, was disapplied following legal action by bereaved families.

The court ruled this part of the act was incompatible with human rights' legislation and the Windsor Framework.

Labour pledged to repeal the Legacy Act if they won the general election in July and formally began that process in December.
