LISBON, Portugal (AP) -- Portugal's conservative president announced yesterday he is ratifying a law allowing gay marriage in the predominantly Catholic country.

The head of state's decision to permit the enactment of a bill passed by Parliament in January makes Portugal the sixth European country allowing same-sex couples to wed.

President Anibal Cavaco Silva said in a nationally televised address, he regretted that the country's political parties had failed to reach a compromise during days of heated debate in Parliament four months ago.

Vetoing the bill would only send it back to Parliament where lawmakers would overturn his decision, he said, adding that the country needed to focus on overcoming an economic crisis that has increased unemployment and deepened poverty.
