The Independent Alliance is to field up to 20 candidates in the upcoming general election.
The group - headed by Independent TD Shane Ross and Michael Fitzmaurice - introduced a number of its newest members at a press conference today.
Journalist Carol Hunt and former Lord Mayor of Drogheda Kevin Callan will stand for the alliance.
Senator Feargal Quinn will be chairman of the grouping and Senator Gerard Craughwell is also supporting the movement.
Deputy Ross said this was not a political party and will not impose any whip except on confidence motions.
He said: “We are radical but we are responsible.”
The press conference was cut short when DÁil ushers said non-members cannot be interviewed on the grounds of Leinster House.
John Halligan TD accused one of the ushers of being biased against Independents.
