In 1986 the execution of six high political figures, including the first Vice President and Minister of Justice Paulo Correia and former Attorney General Viriato Pã, took place.
[1] As a member of parliament Zinha Vaz focused on fighting corruption and abuse of power by government officials.
[1] As a member of the Permanent Commission of the National People's Assembly Zinha Vaz tried to mediate between President João Bernardo Vieira and Brigadier-General and coup-leader Ansumane Mané in the Guinea-Bissau Civil War of 1998–1999.
A coalition government under Prime Minister Caetano N'Tchama was set up in 2000 with help from RGB-MB and Zinha Vaz was made presidential advisor for political and diplomatic affairs.
[5] However, the coalition government fell one year later as RGB-MB politicians in the National People's Assembly managed to pass a motion of no-confidence.
Ialá had called Vaz a traitor of Bissau-Guinean nationalist movement leader, Amílcar Cabral, to the Portuguese PIDE.
[5] Zinha Vaz had responded by saying that when Kumba Ialá was still a member of PAIGC in 1986 he had denounced the victims of the executions that led to the founding of the RGB-MB.
[6] For Ialá the incident had no further consequences as he wished to appoint Zinha Vaz Minister of Foreign Affairs on 31 June 2003.
[7] The Guinean Patriotic Union competed in the 2008 parliamentary elections but did not manage to capture any seats, winning 0,61% of the total vote.

Between 1994 and 1999 Zinha Vaz was also president of the ad hoc Commission of Women and Child of the National People's Assembly.
