Since Spain's December 20 elections produced no clear majority, debate has raged over what sort of government should be formed.
The governing conservative People's Party (PP) won 123 seats in the 250-seat Congress and the right-populist Citizens won 40. On the left, the main opposition Spanish Socialist Workers Party (PSOE) won 90 seats, while radical anti-austerity party Podemos and the three alliances in which it took part together with nationalist forces won 69.
