[5] In 2000, Luisa Fernanda Rudi resigned as mayor of Zaragoza to be President of the Congress of Deputies, and she was succeeded by José Atarés, who brought Azcón into his cabinet.

When Atarés was mayor from 2000 to 2003, Azcón was the councillor in charge of young people, and subsequently he was the party's assistant spokesman when they were in opposition to Juan Alberto Belloch.

[3] Ahead of the 2007 Zaragoza City Council election, new lead candidate Domingo Buesa Conde [es] removed Azcón and two other serving councillors from his list.

[8] In February 2016, when Suárez left the city hall to centre his work on the Congress of Deputies, the party unanimously chose Azcón to be the new spokesman.

A judge ordered its removal, citing a 2020 Supreme Court judgement that public buildings cannot fly unofficial flags at any time, for reasons of neutrality.

[15] In December that year he was chosen as the PP's lead candidate for the 2023 Aragonese regional election, replacing Luis María Beamonte.

[19] In July 2024, Vox pulled out of the government, due to party leader and regional vice president Alejandro Nolasco disagreeing with the accommodation of unaccompanied migrant children (known in Spain by the acronym mena; Menor extranjero no acompañado [es]).
