Hungarian President Laszlo Solyom signed a law which threatens a three-year sentence for anyone who denies that the Holocaust happened, reported Associated Press.
The law was adopted last month by Parliament and later approved by the head of state, who found it does not violate the constitution.
Earlier versions of the draft law, which would have criminalized being pro-Nazi or pro-Hungarian Communist regime, were rejected. The ruling Hungarian Socialist Party and the Jewish community in the country both greeted the new legislation. About 550,000 Hungarian Jews and 50,000 Gypsies were murdered during the Holocaust.
