Support for Eamon Gilmore is growing ahead of the upcoming vote to choose a new leader for the Labour Party.
Mr Gilmore is the only candidate to have so far thrown his hat in the ring for the job vacated by Pat Rabbitte last week.
Labour Senator Michael McCarthy said today that he believed Mr Gilmore was the only man for the job.
The Labour environment spokesman has also attracted support from former leader Ruairi Quinn, Emmet Stagg and Michael D Higgins.
