Recovering its registration in the aftermath of Fujimori's downfall, it became the dominant party of the National Unity coalition, placing third in both the 2001 and 2006 general elections under the candidacy of Lourdes Flores.

In 1968, General Juan Velasco Alvarado staged a coup d'etat against President Fernando Belaúnde Terry, an ally of Luis Bedoya Reyes.

Bedoya Reyes, widely preferred by the Assembly members to become its president, gave the position to the veteran APRA leader, Víctor Raúl Haya de la Torre.

Luis Bedoya Reyes ran as the PPC's candidate for president in the 1980 general election, with Ernesto Alayza and Roberto Ramírez del Villar as his two running mates.

The coalition also designated four PPC members as Ministers, including its leader Bedoya Reyes and Felipe Osterling Parodi.

Its most important representatives were Felipe Osterling Parodi in the Senate of Peru and Javier Bedoya – son of the founder of the PPC – in the Chamber of Deputies.

When Alan García sought to take control of private banking, Luis Bedoya Reyes and Lourdes Flores rallied in the streets against the proposal.

The PPC held the presidency of the Senate under Felipe Osterling Parodi's leadership when, in 1992, Alberto Fujimori staged a self-coup, dissolving both Chambers of the Congress, neutralising the FREDEMO and the APRA.

Fujimori held polls to elect a Democratic Constituent Congress, where his party, Cambio 90-Nueva Mayoría, got an absolute majority.

In the other hand, Luis Bedoya Reyes, Lourdes Flores and Xavier Barrón contended that the PPC should present itself to guarantee democracy in the Constituent Congress.

In the General Elections of 1995, the PPC nominated Lourdes Flores as its candidate for president, but in the end she resigned to support Javier Pérez de Cuéllar's candidacy.

Because of that, Alejandro Toledo's Perú Posible party decided to support the PPC, including Xavier Barrón and Antero Flores Aráoz, as guests in its list for the Congress.

In November of the same year, the PPC achieved victory in the new municipal elections, held to replace the accessories who had entered after the March process.

The result of the electoral process was one of the worst defeats of the party, barely obtaining seven district mayoralties in Lima and its candidate 3% of the votes, remaining in 6th place.

The roundtable managed to negotiate with a variety of political personalities and parties until reaching an agreement César Acuña of Alliance for Progress.

[12] The alliance was officially signed on 12 October 2020, but lasted only six days, upon the revelation of disconformity from PPC's leadership, most prominently from the party Secretary General, Marisol Pérez Tello, who rejected Acuña by stating "she would not support a plagiarizer".
