Singh invited the new Nepal Prime Minister to visit India.
He hoped that Koirala's election will lead to promulgation of new Constitution of Nepal while ushering stability and economic development of that country.
"Your election represents one more important milestone in consolidating and institutionalising recent democratic gains in the course of the political transition in Nepal," Singh said in his congratulatory message to Koirala.
"I am confident that your wise leadership and guidance will further strengthen stability and economic development in Nepal, and foster a climate for promulgation of a new Constitution on the basis of the widest possible consensus and reflecting the will of all sections of the people of your nation," the Prime Minister said.
"As close neighbours with a unique relationship and deep links across all walks of life, our fortunes are closely intertwined. We in India, therefore, not only share the aspirations of the people of Nepal for stability, democracy and prosperity, but also remain steadfast in our support to the Government and people of Nepal in their endeavours to pursue that goal," he said.
Singh's message added, "We will, therefore, continue to seek further deepening of this partnership between our two countries for the benefit of our people and our region."
