After the election, PATT and their sister party South Tyrolean People's Party (SVP) slowly approached the Centre-right coalition. SVP formed both the provincial and the regional government with Lega. In the 2019 European election, SVP–PATT allied with Forza Italia instead of their traditional partner the Democratic Party. In 2021 PATT's Lorenzo Ossanna joined the regional government, including the SVP, the LNT and Forza Italia.[2] Between 2021 and 2022 three PATT provincial councillors out of four, Rossi, Paola Demagri and Michele Dallapiccola, left the party. In November 2022, Demagri and Dallapiccola formed Casa Autonomia.eu, aligned with the centre-left,[3][4] leaving Ossanna as PATT's lone provincial councillor.[5] Between 2021 and 2023 also several other leading members, notably including honorary presidents Luigi Panizza[6] and Dario Pallaoro,[7] left the party and joined CA. Rossi later became a CA supporter.[8]
In the run-up of the 2023 provincial election, the PATT finally decided to support incumbent president Fugatti, thus forming a regionalist/centre-right coalition.[9] Meanwhile, the centre-left coalition supported the independent Francesco Valduga. In the election, PATT and their allies obtained 8.2% of the vote and the election of three candidates, while CA won 4.3% and one seat for incumbent councillor Demagri.[10]
