MARTIN McGuinness could not vote for himself yesterday -- because his home is in Derry.
Although he is an Irish citizen, only those who are 'ordinarily resident' in the State are allowed to vote in presidential elections.
He had to be content with turning up in Bunbeg, Co Donegal, to accompany Sinn Fein's finance spokesman Pearse Doherty to the polling station.
Party president Gerry Adams had a similar problem last year after he failed in his first attempt to be added to the electoral register just weeks before the general election in which he was standing. He was eventually successful in his attempt to vote in Louth.
Mr McGuinness and Sinn Fein have been calling for Irish citizens in the North to have the right to vote in presidential elections --but have not attracted support from the mainstream parties. He was the only one of the seven candidates to be unable to cast a vote for himself yesterday.
Independent Dana Rosemary Scallon cast her vote at Carnmore National School, near her home in Claregalway, Co Galway.
Senator David Norris voted in Marlborough Street in Dublin, close to his home. Mary Davis voted at Burrow National School in Sutton, Dublin.
Fine Gael's Gay Mitchell voted at Kildare Place Primary School in Rathmines, Dublin.
