Fianna Fáil TD John McGuinness has issued a hard hitting Christmas message to his party colleagues accusing "a tiny group of Oireachtas members and unelected party managers" for continuing with the confidence and supply agreement.
The Carlow-Kilkenny TD claimed his party has handed Fine Gael a blank cheque drawn on Fianna Fáil's diminishing balance of goodwill with the electorate.
In an email entitled 'A Christmas message to all in Fianna Fáil', he wrote: "Without consulting the Fianna Fáil Parliamentary Party, our National Executive or members of Fianna Fáil throughout the country, a tiny group of Oireachtas members and unelected party managers has taken a decision to continue with the Confidence and Supply Agreement up to a General Election in 2020."
He said the party was told extending the agreement with Fine Gael was for the good of the country because of the possible impact of a bad Brexit.
However he said few believe that and he described social media comment as overwhelmingly negative and said most political commentators are laughing at the decision to continue.
Mr McGuinness believes Fianna Fáil will be a lamb awaiting slaughter until a General Election in early 2020.
When the election comes he said they will be knocking at doors, hoping to avoid slaughter by explaining to a suffering electorate that they were the good boys in the class.
Concluding the lengthy message, he urged Fianna Fáil members to play a part to shape the future of the party.
"Raise your voice. Demand Change. Fianna Fáil needs you," he wrote.
