Dana Rosemary Scallon is set to announce her intention to enter the presidential race this afternoon.
The former MEP is to make what she is billing as an “important announcement” on the presidential election.
She has been canvassing independent TDs and senators for support for a presidential bid and is also seeking the support of Fianna Fáil.
Meanwhile, RTE has pulled the former Eurovision winner from its Celebrity Bainisteoir television programme as it would be impossible to run the series in conjunction with an election campaign.
Dana ran for the presidency in 1997 when she was beaten by President Mary McAleese.
Dana was due to take part in RTÉ Television’s 8-part entertainment series Celebrity Banisteoir, which went out last night.
RTÉ released a statement today saying that a potential run would cause conflict: “Dana Rosemary Scallon has been cast as one of the bainisteoiri (managers) for the series. If Dana decided to run in this election, it would be impossible to broadcast Celebrity Bainisteoir as it runs throughout the election campaign and results period. In order to ensure RTÉ is unequivocally in a position to comply with our obligations for fairness and balance under broadcasting legislation, Dana has been asked to stand aside.
However, Dana has already appeared in the first and second episodes of the series which will be broadcast before the nomination closing date.
