Sinn Fein has confirmed three of its offices received payments from an emergency fund to support small businesses during the Covid-19 pandemic.
Stormont's Small Business Grant Scheme aimed to support small business in Northern Ireland at the beginning of the first lockdown in March.
MP and MLA constituency offices did not qualify for the fund.
Sinn Fein told the Nolan Show the payments were "unsolicited" and have since been repaid.
In a statement, the party said: "Three Sinn Fein offices received automatic and unsolicited payments of £10,000 under the Small Business Grant Scheme.
"Sinn Fein offices did not qualify and did not apply for the scheme and the monies have been returned to the LPS [Land and Property Services]."
It is understood payments were sent out automatically to 7,000 bank accounts, including to bank accounts of entities now deemed ineligible.
Sinn Fein MLA Maolíosa McHugh's office received the grant and he told the Nolan Show the party had "great difficulty contacting Land and Property Services at the time and getting it paid back to them".
The SDLP, Ulster Unionist Party and Alliance all told the BBC none of their MLAs or MPs received the grant.
An SDLP spokesperson said "The guidance issued states that MP and MLA constituency offices are not eligible for the £10k business relief grant.
"No SDLP MP or MLA has applied for, sought or received a payment for their constituency office."
