The sacrifice made by our party leaders and workers will always be remembered, he said on the occasion.
Singh also took an indirect but sharp dig at BJP's prime ministerial candidate Narendra Modi, saying some leaders of the opposition were using bad language against other leaders and chief ministers of other states but the Congress will desist from doing the same. Modi had attacked Bihar Chief Minister Nitish Kumar at a rally in Patna in Bihar a few days ago, terming him a traitor.
The prime minister also said that some leaders were altering the nation's history and geography at will.
Emphasising the UPA government's performance, he said it h as done much better than the previous NDA government. He said his government has done good work in fields of education and infrastructure and mocked that the BJP only made hollow claims. Singh gave statistical examples to back his claims that the Congress-led Centre had done a good work. He also praised the Food Security Bill of the UPA government, saying it was a historic step.

He said the Centre allocates funds for the development of the backward parts of Chhattisgarh and free them of Maoist influence but alleged that those funds never reach the ground.
He said if elected, the Congress will work for the betterment of education, agriculture, health, employment and technical education in the state.
Singh asked people to judge parties like the BJP carefully, saying they mislead and claimed that only Congress is capable of accommodating all.
