The USL was formed on 5 February 2011[1] initially between the Social Democratic Party (PSD), and the Centre Right Alliance (ACD) of National Liberal Party (PNL) and the Conservative Party (PC).

2012 elections

In June 2012 the USL won the local elections by a landslide. After the elections, in September, the National Union for the Progress of Romania (UNPR), originally a breakaway from PSD and PNL, together with the PSD formed the Centre Left Alliance (ACS)[2] and entered into the USL.

At the parliamentary elections in December, the four-party coalition won about two thirds of the seats in both the Senate and the Chamber of Deputies.[3]


After the Centre Right Alliance of PNL and PC dissolved in November 2013, the PC turned leftwards and aligned more with PSD and UNPR. As a result, the centre-right National Liberal Party broke up the coalition on 25 February 2014 and entered opposition.[4]

In the 2014 presidential election, PSD, UNPR and PC would designate Victor Ponta as their united candidate, while the PNL formed a new Christian Liberal Alliance (ACL) with the Democratic Liberal Party (PDL), supporting Klaus Iohannis.
