"Since I assumed office, I did all in the interest of the nation," he said moving the motion of confidence in his Council of Ministers in the House that began a two-day debate on the issue.
Commending the motion, Singh regretted that the House has assembled for a trust vote after four years of his government at a time when the government had to tackle issues of inflation and price rise.
In a veiled dig at the Left parties which have withdrawn support to his government, Singh recalled the "sagacity, wisdom and visionary leadership" of Jyoti Basu and Harkishan Singh Surjeet, who, he said, were the architects of the coalition government.
In a brief speech moving the motion, he said "I assure the House and the country that every single decision, every policy decision was taken in the fullest confidence that it was in the best interest of the people of the country."
