A review is taking place at Newstalk after stand-in presenter Ivan Yates did not inform the station that he was involved in Fianna Fáil's Presidential Election campaign.
Newstalk has confirmed that Mr Yates operated as a cover presenter on the radio station during three days of the Presidential campaign, Newstalk said in a statement.
"Ivan Yates operated as a cover presenter on Newstalk for three days during the Presidential campaign on September 23rd, 24th and 25th from 9AM-12PM.
"Ivan Yates did not inform Newstalk of any conflict of interest relating to the Presidential election campaign," the broadcaster said in a statement.
This matter is currently under review by Newstalk management, the statement added.
Yesterday, Mr Yates was dropped as the co-host of the Path to Power podcast following the revelation that he provided some advice to Fianna Fáil's failed presidential candidate Jim Gavin.
Mr Yates declined to comment when contacted.
Meanwhile, RTÉ has said that it is satisfied that it has not breached election guidelines during the campaign.
In a statement, RTÉ said that Mr Yates was not used by RTÉ as a presenter or contributor during the Coimisiún na Meán election period.
This ran from 22 September to the close of polling stations on 24 October.
RTÉ confirmed that Mr Yates did appear on programmes before and after this period.
RTÉ indicated that it was not aware of Mr Yates’ role advising Fianna Fáil and that this should have been disclosed to the audience.
Calls for Taoiseach to clarify extent of Yates' election involvement
Attention today has turned to Fianna Fáil and the extent of the party's knowledge of advice given by Mr Yates to Mr Gavin.
The party has so far not revealed the nature of the advice or the level of knowledge or sanction within the party for the involvement of the former FG minister.
In a brief statement this afternoon, a spokesperson for Fianna Fáil said: "As a matter of policy, the party does not confirm the existence or otherwise of any relationships with suppliers or contractors."
Former Fine Gael minister Alan Shatter has called on Taoiseach Micheál Martin to clarify why the connection was not revealed before polling day.
Mr Shatter says that Mr Martin had an obligation to ensure the public were fully informed.
He added that Fine Gael was wrongly accused of smearing president-elect Catherine Connolly on the back of comments from Mr Yates.
Questions to answer
Minister of State for Migration Colm Brophy said Fianna Fáil had questions to answer, but he added that the communications regulator may also have to examine the broadcasting work that Mr Yates did during the election campaign.
"We have regulations around fairness and impartiality that affect broadcasters," Mr Brophy said.
"And we need to look at the work which Ivan Yates did and the comments he was making, which will be made in the context of someone who was involved in campaign which nobody listening at the time knew.
"And I think that's something that a number of broadcasters and maybe the regulator will need to look at."
He said that if Mr Yates was not declaring his involvement to broadcasters, then that raised serious questions.
Mr Brophy also said that it was amazing that nobody from Fianna Fáil declared the connection.
