Terming it a 'magnificent achievement', the prime minister said that Tendulkar had led by example and Indians were proud of his achievement.
Manmohan Singh also wished Tendulkar 'many more glorious years' in cricket.
Tendulkar became the first ever batsman to hit a double century in one-day internationals, scoring an unbeaten 200 off 147 balls against South Africa in Gwalior Wednesday. He broke the record of Zimbabwean Charles Coventry (194 not out) set against Bangladesh last year.
