History would be the best judge of his 10 years at the helm of the UPA government, Prime Minister Manmohan Singh said Thursday.
The prime minister, to a question on whether the scams and alleged wrongdoings like the coal allocation issue would "cast a shadow on his prime ministership", said: "That is for history to judge."
"I am doing my duty and will continue to do my duty. What impact my 10 years of prime ministership will have is for historians to judge," he added.
