In late October 2015, a deadly nightclub fire sparked ample street protests. Within several days, these had swelled to over 25,000 participants in Bucharest alone. Among the demands voiced was the resignation of Ponta, tied within the protesters' ranks to corruption and official indifference. Bowing to pressure, he resigned, citing the "legitimate anger" of the public the "desire to place responsibility at higher levels" than the nightclub owners, and the hope that the expectations of the demonstrators had been met. A technocratic cabinet headed by Dacian Cioloș took office two weeks later; Ponta himself was absent from the confirmation vote. At the 2016 parliamentary election, Ponta retained his seat in the Chamber. In June 2017, he was named secretary general in the government of Sorin Grindeanu, with ministerial rank. In so doing, he was automatically expelled from the PSD, which had agreed to apply this penalty to any party member agreeing to serve under Grindeanu. Shortly after he took on the post, the government was ousted in a no-confidence vote.
