The Green Party chairman, Mr John Gormley, has promised "ethical fundraising" and a programme of "radical party reform" following his re-election to the post.
The Dublin South East deputy received 80 per cent of the votes of party members in a postal ballot with his opponent, Clare County Councillor Mr Brian Meaney, receiving 20 per cent.
Mr Gormley said that he had set out his platform for radical party reform very clearly in the campaign. "The membership have given me a huge mandate for radical party reform," he said.
"I set out my stall very clearly and the membership have responded in an overwhelmingly positive way. I am delighted and I thank them. I would also like to thank my parliamentary colleagues, the party leader and deputy leader for their support."
He said his party needed to cut the amount of time it spent involved in committees and meetings. "Party emphasis must be on communicating our key messages to the electorate and focus on more 'on the ground' engagement with the voters."
He also pledged to improve fundraising. "The party relies mainly on TD contributions and parliamentary allowances. I have promised to change this. We cannot allow our political competitors to enjoy such a clear monetary advantage. The party will be developing a code of ethical fundraising."
He said the Green Party saw itself as a party of government "and we will work tirelessly to replace this discredited Fianna Fáil and PD administration".
