New Delhi, Feb 27 (IANS) Prime Minister Manmohan Singh left for Saudi Arabia Thursday afternoon on a three-day visit, the first by an Indian prime minister to the country's largest oil supplier since prime minister Indira Gandhi went there way back in 1982.

Accompanying the prime minister is a high-level delegation including Minister for Health and Family Welfare Ghulam Nabi Azad, Minister for Commerce and Industry Anand Sharma, Minister for Petroleum and Gas Murli Deora, Minister of State for External Affairs Shashi Tharoor, senior officials and a 25-member CEOs delegation from corporate India.
