Left bloc seen taking the lead in Spain's election - official data
Left wing parties, including the Socialists, anti-austerity Podemos, former communists Izquierda Unida and two other regional groups would jointly total 180 seats, above the 176 mark for an absolute majority.
The ruling conservative People's Party (PP) would garner 123 seats while Ciudadanos, often seen as a potential coalition partner for the PP would get 31 seats.
