Northern Ireland's Deputy First Minister Michelle O’Neill is one of a number of senior Sinn Féin members who will be interviewed by police investigating alleged Covid-19 breaches at the funeral of veteran republican Bobby Storey.
The party has confirmed to RTÉ News that she is one of 14 people sent letters asking them to attend voluntary interviews at a local PSNI station.
Those who received the letters have been given 14 days to respond.
The investigation into the alleged breaches of Covid-19 regulations at the funeral in west Belfast in June is being led by Cumbria Constabulary Deputy Chief Constable Mark Webster.
In a statement, Sinn Féin said: "A number of the party’s elected representatives have received letters from the police this morning asking them to present for voluntary interview.
"They will contact the police and cooperate with the investigation."
She said she regretted what had happened.
An independent probe into events at a Belfast cemetery on the day that Mr Storey was cremated is set to report in six weeks.
Further upset was caused over access granted to Roselawn Cemetery on a day when eight other families were denied access due to pandemic measures.
Belfast City Council apologised to those families.
The council also ordered an independent investigation into the handling of the funeral at Roselawn Cemetery, which will be led by lawyer Peter Coll QC.
It will report back in six weeks' time. The terms of reference include 14 concerns.
The first of these is whether any preferential treatment was sought to accommodate the cremation of Mr Storey by political representatives or others acting on behalf of the family.
The list of concerns also includes whether "control" of the cemetery was handed to persons acting on behalf of the Storey family, using CCTV to examine numbers present and the decision to send council staff home.
Mr Coll has also been asked to "review when and if decisions were communicated to elected representatives, which elected representatives they were communicated to and when they were so communicated".
In a statement, Belfast City Council said families affected by events at Roselawn will be given the opportunity to speak to Mr Coll directly.
"Party Group Leaders on Belfast City Council have agreed to the release of the Roselawn investigation terms of reference," the council said.
"These incorporate the issues raised by the political parties within council following the decision to commission an independent investigation, and have been approved by all of those parties that supported that decision.
"The terms of reference provide scope for additional issues to be raised between Party Group Leaders and Peter Coll QC.
"Council will ensure that any relatives of families impacted may speak directly with Mr Coll QC should they wish to do so.
"Council will be in touch with family representatives in the coming days to facilitate arrangements should they wish such a meeting to take place."
