James Lawless says, however, that Micheal Martin should step aside as party leader in 2022.
A Kildare Fianna Fáil TD says he will not be signing a motion of no confidence in party leader, Micheál Martin.
Several TDs have indicated that they may be prepared to do so, following the party's failure to win the Dublin Bay South By-Election, and a succession of poor showings in opinion polls.
James Lawless says, however, that Micheal Martin should step aside as party leader when his term as Taoiseach ends in 2022.
Deputy Lawless is 4/1, third favourite to become the next party leader.
Speaking to Kildare Today, he says he will confine his ambitions, for the moment, to Cabinet.
Deputy Lawless joined Clem Ryan on Tuesday's edition of the programme on a wider interview.
