Spain still have never had to hold repeated elections. General elections in December 2015, has led to the end of the era of two-party system in the country — before the socialists and the former ruling people's party alternately ruled by Spain for more than 30 years.

The conservative popular party of Mariano Rajoy won the General election, but failed to hold the majority of seats in Parliament and was forced to form a coalition.

At the present time represented in Parliament the party "Podemos", which opposes austerity measures, and the centrist party "Citizens".

Rajoy, who was Prime Minister before the election, he headed the provisional government. He refused the offer of the king to form a government, since the chances of its approval of the rest of the Parliament were minimal.

After the elections on 20 December 2015 no single party won an absolute majority. First with a large number of votes in Parliament has included two new parties — the ultra-leftist "Podemos" and the liberal "Citizens".

Due to partisan differences failed attempts to form a governing coalition, first on the basis of receiving the majority of votes of the conservative people's party (NP), then the second-ranked Spanish socialist workers ' party (PSOE).
