Mr Deasy, a vocal internal critic of Taoiseach Enda Kenny, feels the fact that the position will now be filled by secret ballot gives it a proper mandate to affect change in the Dáil chamber.
The outgoing vice-chair of the Public Accounts Committee has been at the fore of uncovering sex abuse allegations at a foster home in the south east.
Speaking to the Irish Examiner about the role, Mr Deasy said: “Had you asked me six weeks ago, I wouldn’t have said I was interested. I am now. In the new Dáil, this is a serious position and I am interested for it.
“You have a mandate through this position given the secret ballot.
“Because there is a mandate there to the person who wins, the position carries with it a lot of influence, if that person wishes to change things within the Oireachtas.”
Last week, Mr Deasy was given a ringing endorsement by Renua Ireland leader Lucinda Creighton.
She was asked to name a politician from another Irish political party she admired, during the course of a radio interview on Newstalk.
She said:”I admire somebody like John Deasy — who’s considered to be a bit of a renegade in Fine Gael, but he’s, I think, a very straight talker and somebody who I believe has a lot of principles”.
Speaking yesterday, Ms Creighton said Renua would not be putting forward a candidate for the Ceann Comhairle position.
Another Fine Gael TD and former junior minister, Fergus O’Dowd, has already declared his desire to contest the post, while another junior minister, Michael Ring, has also been linked with the post.
Speaking last night, Mr Ring would not be drawn on the speculation, saying his focus was solely on getting re-elected.
Fianna Fáil’s veteran Limerick TD Willie O’Dea has been suggested as a candidate for the party, but several party figures have said they would consider supporting Mr Deasy, given his anti-Kenny feeling.
