Days after the ruling BJP held grand celebrations on the birth anniversary of 'Iron man' Sardar Vallabhbhai Patel, it's the Congress party's turn to showcase its political clout. The Congress party will today formally kick off a two-day long international conference to commemorate the 125th birth anniversary of the country's first prime minister Jawaharlal Nehru amid much fanfare. Barring the NDA allies, the Congress has invited various 'like-minded' political parties from within the country and leaders from abroad for the two-day long international conference on Nehru.
