Dan Barna (USR) and
Dacian Cioloș (PLUS), as leaders of the
alliance, declared on 2 February 2019 that the two parties reached an agreement to participate jointly in European elections and that the project was a first step towards a possible success in the
2020 Romanian legislative election. On 7 March 2019, the
Central Electoral Bureau (BEC) rejected the application for registration of the 2020 USR-PLUS Alliance for the European Parliament elections, motivating that Barna and Cioloș were not listed as presidents of the two parties in the Register of Political Parties. Barna was elected president of the USR in October 2017, and Cioloș was elected president of the PLUS in February 2019. Both requested their registration as presidents at the Bucharest Tribunal, but until the Alliance's registration they did not receive a final decision.
Deputy Nicușor Dan, former president of the USR, declared that "I found, together with the legal team, the solution that would allow me to legally countersign the protocol of the USR-PLUS Alliance". On March 8, the
High Court of Cassation and Justice accepted USR-PLUS' appeal to the decision of the BEC not to allow the alliance to be registered. The alliance's chosen
slogan used to be
Fără hoție ajungem departe, meaning "Without thievery we go far" and referring to the existing
corruption in Romania. Nowadays, the slogan is
O Românie fără hoție ("A Romania without thievery"). On 15 August 2020, members of the USR and PLUS held an online
congress to decide whether to formally unite the two parties or not, with 84.65% of the participants voting in favor of a merger. This new party would still be called USR (Save Romania Union) and would be led by Barna and Cioloș until a judicial decision on the merger was made; then, the party would be renamed to "USR PLUS". The parties, USR and PLUS, officially and legally merged into one single party on 16 April 2021 after the approval of this by the Court of Appeal of Bucharest. In addition, the party was said to be preparing for a new congress, probably held in the autumn of 2021, to vote a single leadership, with Barna and Cioloș announcing that they would both participate in this vote. Subsequently, the 24 members of the National Political Bureau were elected, while it was decided that the statutory name of the party remains
Save Romania Union. ==2019 European Parliament elections==
