ANKARA - Turkey's fledgling conservative government is likely to collapse by the end of the week, observers said after deputies voted yesterday to submit it to a no confidence motion. The vote on Mr Mesut Yilmaz's government, which will be held on Saturday comes after weeks of political bickering with its coalition partner party, led by the former prime minister, Ms Tansu Ciller. She withdrew the support of her centre right True Path Party last week in a move which prompted the main opposition pro Islamic Welfare Party to call for a no confidence vote.
