A petition to have Conor McGregor's image featured on the €1 coin was deemed inadmissible at the Oireachtas as the petitioner could not be contacted.

UFC superstar McGregor's sensational year, in which he claimed the featherweight title after an explosive 13-second knockout victory over Jose Aldo in December, saw levels of support grow even further with the petition put forward by Patrick O'Leary.

It was received by the Oireachtas in mid-December to be discussed by the Public Petitions Committee at Leinster House this afternoon.

McGregor tweeted prior to the committee meeting: "It would be a true honour for me to be immortalised on the €1 coin! Thank you to my fans for the petition! Let's go Oireachtas! Vote yes."

But committee chairman Pádraig MacLochlainn TD revealed that they were unable to contact O'Leary and as a result couldn't proceed.

The committee suggested the petitioner contact Central Bank should he wish to take the matter further.
