Spain's conservative People's Party (PP) won an overall majority in the parliament of Galicia, while the Basque Nationalist Party (PNV) came out on top in the Basque Country, in regional elections on Sunday.
According to official results, the PP took 47.5 per cent of the vote in Galicia, winning 41 of the 75 seats in the regional parliament.
The grass-roots populist Podemos movement achieved 19 per cent, beating the Socialists, who won 17.8 per cent, leaving both with 14 seats each, while the Galician nationalists garnered six seats.
In the Basque Country, the nationalists, who have been the ruling power in Basque Country since 2012, won 37.6 per cent of the vote, giving it 29 seats in the 75-seat parliament.
Basque separatists won 17 seats, followed by Podemos on 11. The PP and Socialists both came away with nine seats apiece.
Some 4 million were eligible to vote in the polls that could affect a political stalemate in the capital, Madrid.
Acting Prime Minister Mariano Rajoy will be buoyed by his party's success in his home region of Galicia, where it has been in power for the last four years.
Spain has not had a functioning government for almost nine months.
Earlier this month, the parliament rejected Rajoy's latest attempt to win a confidence vote to form a new government, edging the country closer to a third election in a year.
