Labour Party chief whip Emmet Stagg welcomed
The Galway East TD criticised his former colleagues for promising to do "one thing then do another and blame it on someone else" in a series of hard-hitting statements on Twitter.
“Since he resigned the whip, he has consistently attacked Labour, thereby betraying the party members who elected him as chair,” Mr Stagg said.
“Labour Party public representatives around the country with the support of loyal party members will continue with the job that we were elected to do to fix our broken economy, create employment, and improve the livelihoods of those we represent.”
He confirmed vice-chair Loraine Mulligan is to become party chairwoman.
Meanwhile, Labour TD Robert Dowds said he was “absolutely disgusted” by Mr Keaveney, claiming he was well aware of the challenges the party faces in getting the country back on its feet.
He said Mr Keaveney had let down Labour voters, members of the party and the country with his actions.
“He has walked away because he doesn’t have the courage to face the difficult situation that we live in,” Mr Dowds said.
