The Sinn Féin leader says it's time the Irish government increased the pressure on Boris Johnson so a public inquiry into Pat Finucane's murder takes place.
It follows yesterday's announcement by the British government that it would not go ahead "at this time".
The murder of the Belfast solicitor in 1989 by loyalist paramilitaries is seen as one of the most notorious of the Troubles, as it was found to have involved collusion with the UK state.
Sinn Féin leader Mary Lou McDonald says she'll be raising the issue of the public inquiry in the Dáil later:
"It's an intolerable situation. There had been an agreement, remember, between the British and Irish governments that a judge would be appointed. Judge Cory was appointed; he reported back and he said there needs to be a public inquiry into Pat Finucane, and yet here we are years later and the family's still left in this limbo."
