Ireland's three main parties are tied in first place following Saturday's general election, an exit poll forecast, leaving the battle to lead the next government too close to call. Prime Minister Leo Varadkar's Fine Gael party, centre-right rivals Fianna Fail and left-wingers Sinn Fein all received 22 per cent of first preference votes, according to the PSOS MRBI poll issued as the polls closed at 2200 GMT. jts/rjm/pma
