The Irish and British government's are set to unveil a new agreement on dealing with the legacy of Northern Ireland's Troubles.
The joint framework will be published at a news conference later today.
It will include commitments by both governments to legislate for changes which have been agreed.
Among expected developments are the renaming of a controversial investigative body.
The Independent Commission for Reconciliation and Information Recovery - established under the UK's controversial Legacy Act - will be retitled the Legacy Commission.
It will be reformed to include a new independent oversight board and robust conflict of interest rules for staff.
Its job will be to investigate cases and take criminal prosecutions where the evidence supports them.
There will be a separate fact finding body, the Independent Commission for Information Recovery (ICIR) which can provide reports to families.
There will be an arrangement where information provided to the ICIR by interlocuters on behalf of paramilitary groups can't be used in criminal cases - closely mirroring a mechanism used by the so-called Disappeared Commission.
The Irish Government will legislate to ensure the fullest possible co-operation by the authorities in the Republic with the reformed legacy institutions.
It will also commit to undertake investigations in the Republic.
It is expected to set aside €25 million to support families in legacy processes.
A new legacy unit will also be established in An Garda Síochána as a single point of contact in such cases.
Talks have been going on for a year between the two governments to reach the agreement.
A key objective has been to develop proposals which are both compliant with the European Convention on Human Rights and have the support of families.
In 2024, the Irish Government took an interstate case against the UK to the European Court of Human Rights on the grounds that the current legislation was in breach of the convention.
It is expected that once the new framework is translated into law, that decision can be reviewed.
The UK's Labour Government inherited the existing Legacy Act from their Tory predecessors.
British Prime Minister Kier Starmer promised to repeal and replace it, with Northern Secretary Hilary Benn promising fundamental reform.
There have been high level discussions on the issue involving both the Taoiseach and the Tánaiste.
The new arrangements closely resemble the legacy elements of the 2014 Stormont House Agreement between the two governments and most of Northern Ireland's parties.
That agreement was never implemented.
It is expected that work to translate the new framework into legislation will take time.
A commitment will also be given to transfer any investigations already under way in Northern Ireland into the new institutions.
The political parties in Northern Ireland have been briefed on the plan.
The British and Irish Governments have been keen to resolve their differences over legacy issues as part of a wider reset of Anglo-Irish relations with the coming to power of the Labour government.
