Polling stations opened Friday as Ireland voted for a second time on whether to adopt the European Union's Lisbon Treaty, AFP reported.
The polls opened at 7:00 am (0600 GMT) and are due to close 15 hours later at 10:00 pm (2100 GMT).
European leaders are anxiously hoping for an end to the constitutional deadlock gripping the 27-nation bloc since June 2008 when Irish voters rejected the treaty -- which aims to streamline EU decision-making -- by 53.4 percent.
