Bulgaria's centre-right GERB party, which came first in an election last Sunday, urged the country's political parties to put a new government in place "whatever the cost" following the fifth inconclusive poll in two years.
Bulgaria faces lengthy government-building talks or the prospect of another vote, prolonging political instability in the European Union member state that has been fuelled by distrust between the pro-Western reformist party PP, which came second, and GERB, the party of former prime minister Boyko Borissov.
