Political career

Adrianzén began his political career in 2015 when he was appointed Deputy Minister of Justice and Human Rights.^[3] Only two weeks later, on 2 April, he was appointed Minister of Justice and Human Rights, replacing Fredy Otárola.^[4] In October, then Money Laundering Prosecutor Julia Príncipe claimed that Adrianzén tried to “gag” her by asking for explanations for her statements to the press regarding the investigations involving First Lady Nadine Heredia. Adrianzén was summoned to Congress to account for these allegations but resigned on 20 October^[4] to avoid impeachment. Príncipe was also relieved of her position.^[2]

He was appointed by president Dina Boluarte to the post of permanent representative of Peru to Organization of American States (OAS) on 23 February 2023. As ambassador, he expressed the "unwavering and unwavering commitment of the government and people of Peru to the values" of the OAS. He resigned in March 2024 following his appointment as prime minister by President Boluarte.^[5]

On 6 March 2024, he was sworn in as Prime Minister of Peru, following the resignation of predecessor Alberto Otárola for his controversial involvement in the hiring of Yaziré Pinedo whom he referred to as "my love" at the Defense Ministry.^[2] He resigned on 13 May 2025 shortly before a scheduled no-confidence vote against him in Congress.^[6]
