Kochi, April 07 (ANI): Prime Minister Manmohan Singh lashing out at Bharatiya Janata Party, said that the Congress alone could counter the "divisive ideology" of BJP and its misleading propaganda against the ruling government in handling graft cases as well as developmental issues. Singh addressed a public rally in Kochi in Kerala endorsing the economic development achieved during the Congress led UPA government. While addressing the rally, Singh also took jibes at the Left saying that its stock was bound to dwindle further in the future unless they changed in tune with the times.
