Spain's ruling conservatives on Saturday voted to keep Prime Minister Mariano Rajoy as their leader, after a wave of high-profile corruption scandals threatened to push the party out of power.

Spain's King Felipe VI is to meet Sunday with Saudi King Salman, local media said, during an official visit coinciding with talks to sell Spanish warships.

Spain's conservative leader Mariano Rajoy was sworn in Monday for a second term as prime minister, bringing a close to 10 months of political limbo.

One person died and 14 people were injured in an explosion in a block of flats in a Spanish seaside resort near Barcelona early Sunday, rescuers said. 

Spain's acting Prime Minister Mariano Rajoy said he would make a push for power after his conservatives won more seats in parliament in a repeat general election on Sunday, even though it still fell short of a majority.

His Popular Party (PP) was the big winner of the election, the second in six months, which played out amid the turbulence from Britain's shock vote to leave the European Union.

Spain's anti-austerity party Podemos and its allies could leapfrog the Socialists in this month's repeat general election to become the country's main opposition, three polls showed Sunday.

The surveys published in El Pais, El Mundo and El Espanol dailies showed acting Prime Minister Mariano Rajoy's conservative Popular Party coming first, with 27.7-31 percent of the vote, way short of a parliamentary majority.

An unemployed man who drove a car loaded with a home-made bomb into the Madrid headquarters of Spain's ruling Popular Party (PP) has been sentenced to five years in jail, a court said Monday.

In December 2014, Daniel Perez Berlanga rammed a car with an explosive device made up of gas cylinders and fertilizer through the glass front of the building, reaching a staircase inside.

Spain's King Felipe VI met with political party leaders on Monday in a last desperate bid to get them to form a coalition government -- and avoid calling the country's second general election within six months.

The monarch will wrap up the talks -- his third round since an inconclusive December 20 election -- on Tuesday by meeting with acting Prime Minister Mariano Rajoy, who said over the weekend he was ready for new polls.

The head of a Spanish anti-corruption group that championed several high-profile cases over the past two decades, including one against Princess Cristina, now finds himself under investigation for extortion.

A judge this week ordered the founder and leader of "Manos Limpias" (Clean Hands), retired Madrid city hall employee Miguel Bernad, 74, to be remanded in custody while a probe is conducted into a blackmail and extortion ring he allegedly ran.

Four lawmakers from Spain's far-left party Podemos and its allies are said Wednesday they are on a week-long hunger strike to try to rally public support of refugees.

The lawmakers began their hunger strike on Saturday and are calling on people to occupy public squares for 24 hours on Friday, the day they plan to end their action , in a gesture of support for those people at the center of Europe's biggest migrant crisis since World War II.
