The protracted process of counting votes in Ireland’s General Election will begin as an exit poll put the three main parties virtually tied.

The selection by Fine Gael of Senator John McGahon in Louth has also dogged the Taoiseach’s campaign. Mr McGahon was found not guilty of assaulting a man outside a Dundalk nightclub in a criminal case two years ago, but a civil action earlier this year found him liable and he was ordered to pay damages.

The two main parties in the outgoing Irish government have again ruled out Sinn Fein as a potential coalition partner in the next government. The leaders of Fianna Fáil, Fine Gael and Sinn Féin were taking part in a TV debate just days before the general election.
