Turkey's Prime Minister Tayyip Erdogan on Thursday said his government seeks to draft a new constitution by the first half of 2012 as a step aimed at updating the constitution, which was written under military tutelage after a 1980 coup. The Government would seek cross-party consensus to do so, he added. "We will focus on the new constitution intensely with the start of new term in parliament. I hope rapidly, within the first half of 2012, we want to get this finished," Erdogan told reporters here before heading to Macedonia.
