Political career
He was first elected to the Knesset in the 1999 elections on the National Religious Party list. After being re-elected in the 2003 elections, Orlev was appointed Minister of Welfare and Social Services in Ariel Sharon's government. During the crisis in the party over the Gaza disengagement plan, Orlev led the camp which believed staying in the government, rather than leaving the coalition, was the best option. In response, NRP leader Effi Eitam called Orlev a "Meimadnik". When Eitam and Yitzhak Levy quit the government in 2004, Orlev and many NRP members refused to leave the coalition. Orlev then succeeded in taking control of the party, resulting in Eitam and Levy leaving to form the Renewed Religious National Zionist Party, which would later join the National Union. Orlev was re-elected in the 2006 elections. Prior to the 2009 elections the NRP was dissolved and its members joined the Jewish Home. Orlev won second place on the new party's list, and retained his seat in the subsequent elections. Orlev became known for several controversial statements and legislative proposal. In 2009 the Knesset debated a Private Members Bill proposed by Orlev, providing for imprisonment of anyone who denied that Israel was a Jewish and democratic state. The bill passed its preliminary reading. Orlev was criticized for proposing a bill that would mandate divorced fathers to pay child support until their children reached age 22, though he later retracted and stated he would not pursue the bill. In 2012, he called for the Third Temple to be built in Jerusalem, as well as legislation to protect the project from prosecution and the "hostile, secular, left-wing media". He also proposed a Private Members Bill to override an Israeli Supreme Court ruling ordering the demolition five buildings in an Israeli settlement. Orlev did not run in the 2013 elections. He is a co-president of the internationalMizrachi movement, which the National Religious Party and its successor Jewish Home represents in the political arena.
