The party has had several associated members and regional partners. At the European level, it is a member of the European People's Party. Most of NM's members and elected officials are former members of Forza Italia.
In May 2023 NM evolved into a unitary party,[5] causing the splits of CI[6] and the UdC. Maurizio Lupi, leader of NcI, became NM's leader and president, while Giovanni Toti, leader of IaC, was appointed president of the party's national council during the party's first congress, held in October 2023.[7][8] In January 2024 Italy of Values (IdV), formerly aligned with the centre-left, joined and its leader Ignazio Messina became NM's spokesperson.[9] In February UdC leader Lorenzo Cesa aligned his party with the League[10] and subsequently left NM's group in the Chamber.[11]
In September 2024 Mara Carfagna, Mariastella Gelmini and Giusy Versace, all three former FI members who had joined Action in 2022, formed an association named "Popular Centre". In October they officially joined NM, as well as its parliamentary groups in the Chamber and the Senate.[12]
In November 2024 NM changed its symbol, adding to its name also "Populars for Europe", and it was announced that the party was seeking to join the European People's Party (EPP) in the coming months.[13][14][15][16] The party was officially admitted into the EPP in January 2025.[17] In March 2025 Carafagna was appointed secretary,[18] while in July Ilaria Cavo president of the national council, replacing Toti.[19]
