Seán Canney has informed the Taoiseach that he has resigned from his role as Assistant Government Whip.
The Galway East TD said his decision was taken because he did not want anything to destabilise the Government.
Mr Canney left the Independent Alliance last week.
He said that move was never about positions or jobs but rather about trust and principle.
He indicated when resigning from the grouping that he intended to continue to support the Government on issues of confidence and budgetary matters.
The task of co-ordinating the Independent Alliance will now be handled by Junior Minister John Halligan.
Mr Halligan will not receive any payment for this work.
This comes after the four Independent Alliance ministers met the Taoiseach this morning.
There is speculation the Chairperson of the Oireachtas Housing Committee, Fine Gael TD Maria Bailey, could replace Mr Canney as Assistant Whip.
The job comes with an annual payment of €15,000.
Should Ms Bailey be promoted then the way would be clear to appoint Mr Canney as the new chairperson of the Oireachtas Housing Committee.
That post pays an extra €9,500 a year on top of a TD's salary.
Mr Canney, who is a chartered quantity surveyor, has previously expressed an interest in helping the Government on housing issues.
