ANKARA (AFP) - Turkish Prime Minister Recep Tayyip Erdogan lashed out at the EU and said it "should not become involved in Turkey`s internal affairs."

He was referring to a statement earlier Friday by an EU spokesman expressing concern at a penal code reform bill crucial to the country`s EU bid being left in parliamentary limbo.

Erdogan`s Justice and Development Party (AKP) unexpectedly blocked its own bill Thursday night, while it was in the very final stages of enactment by parliament, in the face of internal pressure from its hardline Islamist wing to introduce a clause making adultery as a criminal offence.
