Former Taoiseach John Bruton has said he will not be contesting the Presidential election.
Mr Bruton said he had been asked by Fine Gael to allow his name go forward for selection as the party's candidate in the election later this year.
He said: 'I discussed the matter thoroughly with the party's representative. I promised to reflect carefully on the request and respond.
'I did so about ten days ago. I said, with regret, that I did not wish my name to be among those considered.'
He said it was a 'very great honour to have been asked', but he will now support whoever is selected as the Fine Gael candidate.
Mr Bruton also said that at no time in the discussions did he request that the role of the President be expanded or altered.
