Addressing an election rally of the Congress at Bhongir town of Nalgonda district, about 50 km from here, he said the some Bharatiya Janata Party leaders through their statements openly tried to create a divide in the society.
"Though BJP later tried to distance away from these statements, I believe attempt to divide the society is an inseparable part of BJP's politics. The statements have come at a time when some states are going to polls where BJP think politics of division will benefit them," the prime minister said at his first election meeting in Telangana.
He urged people to decide whether a party which divides the society should form the government and whether they will vote for a party which makes one community fight against the other.
Without naming the BJP's prime ministerial candidate Narendra Modi, he said BJP's election campaign centered around one man. "They are only talking big which has no basis and they are making promises which they can never fulfill," he said.
Prime minister since May 2004, Manmohan Singh has already declared that he is not seeking a third term and will demit office after the 2014 Lok Sabha polls.
He dismissed as baseless the allegations by political rivals that the government did not make all the efforts to curb corruption. He claimed that no government in the past made efforts as the United Progressive Alliance ( UPA) government made in the last 10 years to check corruption.
Manmohan Singh said in the cases of irregularities which came to the government's knowledge, it ensured that guilty are punished.
Describing the Lokpal bill a major step in controlling corruption, he said the government wanted to bring more new legislations but the BJP did not cooperate in parliament. "I am presenting these facts before you so that you know the real picture of the parties which talk big on controlling corruption."
Listing out the achievements of his government, the 81-year-old economist claimed that the development which the country witnessed during last 10 years was never achieved in any other decade in the past.
"The UPA II government did its best to live up to your expectations. In many sectors we achieved a lot but in some sectors the achievements were not to the level we had expected."
He claimed that the poverty declined by three times between 2004 and 2011 and about 14 crore people were lifted out of poverty.
He listed out the schemes implemented in agriculture, education, healthcare and the steps taken to improve the infrastructure.
Seeking another mandate for the Congress, Manmohan Singh said the party would redouble its efforts for development and to remove hunger, disease and illiteracy and to create new job opportunities.
