GREEN Party leader Eamon Ryan has warned that abolishing the Seanad will only concentrate power in a "smaller political circle".
At the launch of the Green Party's Seanad referendum campaign, Mr Ryan called for a 'No' vote to force the "Abolition is not reform.
You get a smaller political circle but an unchanged political circle in power," he said.
Mr Ryan also accused the Government of 'arrogance' in declaring that it would not reform the Seanad if there was a 'No' vote.
"I don't think they could refuse the political will of the people which would be expressed by a 'No' vote in this referendum," he said.
The Greens were one of the few parties in the 2011 General Election not to call for the abolition of the Seanad.
However, the party was decimated at the general election after its role in Government, with all six of its TDs losing their seats.
