Over 36 million Spaniards will flock to the polls on Sunday December 20, 2015 to vote for 350 members of the parliament and 208 senators. For the first time since 1982, the two traditional Spanish political parties, right-wing Partido Popula (People's Party) and centre-left wing Partido Socialista Obrero Espanol PSOE (Spanish Socialist Workers' Party), are holding a tight election race with two new contenders, Ciudadanos (Citizens) and Podemos (We Can) attracting right-leaning and left-leaning voters respectively.
