Spain is going to the polls in parliamentary elections in a race that is still too close to call. For the first time in years, outside parties pose a serious challenge to the country's traditional two-party system.
Voting stations open at 9am local time (08.00 UTC) on Sunday as Prime Minister Mariano Rajoy and his conservative People's Party (PP) brace for a major fight.
For the first time since the era of dictator Francisco Franco came to an end and democracy was introduced, outside parties threaten to upend the country's two-party system.
The PP is running for a consecutive four-year term in office. However, the emergence of two new left-leaning parties - Podemos and Ciudadanos - is posing a major challenge.
Ciudadanos ("Citizens") lies to the right of the Socialist Party (POSE) in Spain's political spectrum. Its polished leader, Albert Rivera, is known to be pro-business and socially liberal.
Podemos, the other party to burst onto the scene, was formed in 2014 and has gained popularity thanks to its aggresive anti-austerity platform.
Finally, there is the Socialist Part (PSOE), the PP's traditional rival. Pedro Sanchez, the PSOE's current leader, has a lot to prove after the party's humiliating defeat in 2011. The PSOE is widely expected to come in second place.
Polling stations close at 8pm local time (1900 UTC).
