Former presidential candidate Sean Gallagher is writing to the Minister for Communications Pat Rabbitte this morning to request a public inquiry into the 'Frontline' Presidential debate on RTE.
Mr Gallagher is drafting the letter with his legal advisors this morning.
In a statement yesterday, Mr Gallagher described an allegation in the Sunday Independent, that a 'Frontline' audience member's question was changed by a researcher as "disturbing".
He said we now need to find out if RTE compromised the democratic process.
The Broadcasting Authority of Ireland last week upheld a complaint from Mr Gallagher relating to a bogus tweet read on the debate.
Fianna Fáil's Communications Spokesperson, Niall Collins, supports the call for a full inquiry and is also critical of the BAI's report into the matter.
