MADRID (Reuters) - Spain will hold its fourth election in four years on Nov. 10 after rival parties failed to break a months-long impasse in a deeply fragmented parliament, with no guarantee the repeat vote will make it any easier for them to form a government.
Spain, with the fourth-largest economy in the European Union's euro currency zone, has been in political limbo since the Socialists emerged as the biggest party in a parliamentary election in April without enough seats to govern on their own.
Party leaders have spent more time blaming one another for the impasse than negotiating to put together a government, and a flurry of last-minute calls and initiatives on Monday and Tuesday failed to achieve a breakthrough.
"There is no majority (in parliament) that guarantees the formation of a government, which pushes us into a repeat election on Nov. 10," Socialist leader Pedro Sanchez told an evening news conference.
Sanchez, who became prime minister in June 2018 when the conservatives were ousted over a corruption scandal, stayed on as acting premier after the April snap election
Opinion polls show a new election might not end the impasse, with the Socialists winning more seats but still unable to win enough seats in the 350-member parliament to secure a majority on their own.
Although Spain's economy has not suffered greatly, financial analysts say further delays in implementing reforms in areas such as labor and pensions could finally start to bite.
The blame game among main party leaders hit full speed as soon as the snap election was announced, with Sanchez pinning the blame squarely on the opposition and the opposition saying it was all his fault.
"Pedro Sanchez had a mandate to form a government. But he didn't want to. Arrogance and disdain for the basic rules of parliamentary democracy have come before common sense," the leader of far-left Unidas Podemos, Pablo Iglesias, tweeted.
Podemos and the Socialists tried and failed for five months to agree on a government deal.
The leaders of the right-wing People's Party (PP) and Ciudadanos also slammed Sanchez.
"He wanted elections from the beginning and that's why he hasn't tried to form a government," PP chief Pablo Casado said, echoing similar comments from Ciudadanos leader Albert Rivera.
Spain has been struggling to put governments together since new parties including Podemos, Ciudadanos and the far-right Vox started appearing five years ago. Before that, PP and the Socialists dominated the country's political landscape for decades.
'NOT SUFFICIENTLY AFRAID'
Spain was forced to repeat the December 2015 election in June 2016 after no single party succeeded in forming a government and repeated attempts to agree on a coalition failed.
There have been no major fiscal reforms since 2015, when then-Prime Minister Mariano Rajoy's majority PP government framed the 2016 budget. After that, budgets were rolled over or approved late for just half a year.
With voters weary of being called so often to the ballot box, the level of abstentions will be key on Nov. 10.
Asked why they had not been willing to make more compromises, Socialist officials have repeatedly pointed to a lack of trust between themselves and Podemos.
Podemos officials, in return, have said the Socialists simply wanted to "humiliate" them and never negotiated seriously.
"Neither the Socialists nor Podemos were sufficiently afraid of new elections," said Pablo Simon, a political science professor at Madrid's Carlos III university. "There hasn't been a serious negotiating process."
One aide close to Sanchez told Reuters recently that a repeat election, however inconclusive, could encourage centre-right parties, and in particular PP, to allow Sanchez to be voted in as premier to avoid the uncertainty of yet another repeat vote.
