Spanish elections delivered a hung parliament for the second time in six months on Sunday, adding to political uncertainty in Europe after last week's shock Brexit vote and piling intense pressure on Spain's warring politicians to form a government.
Acting Prime Minister Mariano Rajoy's centre-right People's Party (PP) again emerged with the single biggest bloc of seats but fell short of a majority, leaving the euro zone's fourth-largest economy at risk of another lengthy political stalemate.
The PP was the only major party to increase its share of seats from December's inconclusive poll, sapping the power of a wave of new parties which had fed on years of deep recession and public anger over corruption scandals within the major parties.
"We have won the elections," Rajoy told hundreds of cheering supporters outside PP headquarters in Madrid late on Sunday. "We claim our right to govern."
The PP won 137 seats, up from 123 in December but short of the 176 needed for an outright majority.
