'Yes to Lisbon' campaigners pose for photographers in Dublin, Ireland, on Wednesday. Irish people will go to the polls for a second referendum to decide the future of the Lisbon Treaty on Friday. If accepted, the Lisbon Treaty could finally come into effect eight years after European leaders launched a process aimed at making the European Union "more democratic, more transparent and more efficient," attempting to streamline EU institutions. The Lisbon Treaty was rejected by Irish voters, who saw it as a threat to national sovereignty.
