forces, the PDM, the Alliance "Our Moldova" and Social and Liberal Party (SLP) established the Democratic Moldova Block (DMB). Following the parliamentary elections held on 6 March 2005, the PDM won 8 seats in the parliament, being the only party which had lost the election in 2001 and came back in the parliament in 2005. In October 2007, the Social and Liberal Party MPs joined the PDM's parliamentary group and the number of Democrats increased to 11, and the PDM became at that time the third political force in the Parliament. After merging of the PDM with the Social and Liberal Party, which took place at the Congress on 10 February 2008, Dumitru Diacov was re-elected as a chairman of the party, and former Social and Liberal Party leader Oleg Serebrian became the deputy chairman. The PDM's party hymn became the Beethoven's "Ode to Joy", which symbolizes the pro-European vector of the party and its adhesion to the European federalist flow. On 19 July 2009, Marian Lupu was elected as party chairman at the Extraordinary Congress of the PDM.

Marian Lupu, the PDM's candidate, was delegated as the candidate of the Alliance for European Integration for the position of the President of the Republic of Moldova at the elections held on 10 November and 7 December 2009 but did not gain enough votes. Following the early parliamentary elections of 28 November 2010, the PDM won 15 seats in the Parliament and became one out of three components of the AEI-2.

In May 2013, PDM (with 15 MPs), the Liberal Democratic Party of Moldova (31 MPs) and the Liberal Reformist Party (7 MPs) established the new governing coalition - the Pro-European Coalition. Following the parliamentary elections of 30 November 2014, the PDM won 15.8% and formed the pro-European governing coalition, having 19 MPs in the Parliament of the Republic of Moldova. After the elections, the PDM and Liberal Democratic Party (23 MPs)
