Lawmakers in Portugal have voted to override a veto on a bill that grants full adoption rights to gay and lesbian couples, giving gay couples the same adoption rights as straight couples.

Parliament approved the bill in November, but President Anibal Cavaco Silva refused to sign it into law.

Silva called the change radical and in need of broader public consultation. He said that he was uncertain whether the changes were in the best interest of children.

A majority of 116 votes were needed to overturn Silva's veto. It received 137 votes.

Portugal in 2010 became the eighth country in the world to allow gay couples to marry. Silva signed the law approved by the Portuguese Parliament.
