Immediately after the revolution, basic democratic rights were re-established in Portugal. On 27 April, political prisoners were freed. On 30 April, Álvaro Cunhal returned to Lisbon, where he was received by thousands of people. May Day was commemorated for the first time in 48 years, and an estimated half million people gathered in the FNAT Stadium (now 1 May Stadium) in Lisbon to hear speeches by Cunhal and the socialist Mário Soares. On 17 May, the party's newspaper, "Avante!", produced the first legal issue in its history.
