At the 2004 local elections, the majority of Hungarian Civic Union candidates were enrolled as independents or on common lists with the People's Action (AP) party. The best result was obtained in Harghita County, where three HCU candidates were elected to the county council. Jenő Szász, the president of the HCU, was also re-elected as mayor of Odorheiu Secuiesc, with 51.5%[7] of the vote.
The party presented candidates to the 2008 local elections, gaining approximately 37% of the vote in the Székely Land, but did not participate in the nationwide 2008 Romanian legislative elections to Parliament in Bucharest.
Cooperation with the Democratic Alliance of Hungarians in Romania
In 2014, the Hungarian Civic Party signed a settlement with the Democratic Alliance of Hungarians in Romania (UDMR/RMDSZ) about cooperation and joint support for Hungarian autonomy.[8]
For the EP election 2019, the MPP tried to create a joint list with the RMDSZ, but failed. The chairman of the MPP, said that they would encourage their sympathisers to go to the election and vote in such a way that there would be a "stronger Hungarian representation" in the European Parliament.[9]
