Fianna Fáil's Billy Kelleher has set out his intentions to seek a nomination to run in the European elections, by lining the entrance of the party's Ard Fheis in Dublin with campaign posters.
Mr Kelleher made the statement just days after party leader Micheál Martin said he wanted him to stay in the Dail.
In an interview with the Cork Echo on Wednesday, Mr Martin said Fianna Fáil cannot win a seat in Cork North-Central without Mr Kelleher on the ticket.
He said the party's strategy is to win three seats in the European elections without losing any TDs.
Commenting on the posters, Mr Kelleher said "there is no secret" that he wanted to run for the European Parliament.
He said the ard fheis "is where you have a concentration of delegates, and I am hoping to engage with as many delegates as possible and convince them that I would be a good MEP for Ireland South."
Barry Andrews has addressed delegates and said it is a "huge honour" for him to be nominated to contest the elections on behalf of Fianna Fáil in Dublin.
The party currently has no MEPs after Brian Crowley - who was previously expelled from the parliamentary party - announced his retirement.
In the ard fheis programme, Mr Martin paid tribute to Mr Crowley, saying his life has been "one of service to his community and to the country."
He said: "His personal story has also acted as an inspiration to many people as he refused to allow his disability, following an accident at 16 years of age, to hold him back from his vocation of public representation."
