The elections were held on 30 October. The Alfonsín–Martínez ticket won with 51.7% of the vote, followed by Luder–Bittel with 40.1%. It was the first time since the rise of Perón that the Peronist party was defeated in elections without electoral fraud or proscription. The UCR won 128 seats in the Assembly, forming a majority; and 18 seats in the Senate, constituting a minority. 18 provinces elected radical governors and 17 elected governors from either the Justicialist or local parties. Alfonsín took office on 10 December, and gave a speech from the Buenos Aires Cabildo.
