Newly elected deputies are taking their seats in the first session of the Spanish Parliament following an inconclusive election Dec. 20 that has left the formation of the next government still undecided.

Soon after Wednesday's opening session, King Felipe VI will meet with party leaders to see who is in the best position to form a government.

The governing conservative Popular Party won 123 seats but lacks a majority in the 350-member chamber. The leading opposition Socialists won 90 seats, followed by far-left Podemos and allies with 69 and centrist Ciudadanos with 40. The remaining 28 seats went to six small parties.

Traditionally, the monarch invites the election winner to form a government but can opt for other party leaders if they can deliver a more stable option.
