Young Fine Gael launched a poster campaign today urging people to vote yes to the Lisbon Treaty.
The youth wing of the main opposition party launched the posters, which may raise a few eyebrows.
Fine Gael leader Enda Kenny says Young Fine Gael are an autonomous wing of the party and are doing their own thing.
There are two posters, which target male and female voters, with the slogans: 'Enlarge your opportunities, vote yes to Lisbon' and Increase your prospects, vote yes to Lisbon'.
Slovakia approves Lisbon Treaty
Separately, the Slovak parliament has approved the Lisbon Treaty after an opposition party dropped its threat to derail the motion.
Ratification of the European Union's reform treaty, designed to overhaul the EU's institutions and decision-making, was at risk because the Slovak opposition had threatened to boycott the vote in protest against unrelated media legislation.
But leftist Prime Minister Robert Fico secured the three-fifths majority needed to approve the treaty in the 150-seat parliament after the ethnic Hungarian SMK party broke opposition ranks and voted in favour of the document.
Poland also definitively ratified the EU's Lisbon Treaty today, as Polish President Lech Kaczynski signed the treaty into law.
