MADRID—Prime Minister Pedro Sanchez’s Socialists may lose control of the southern Spanish region of Andalusia after the center-right Ciudadanos party on Monday ruled out any coalition with them after an inconclusive election.

Although the Socialists topped the poll, their position severely weakened in a region that they have governed since the end of Francisco Franco’s dictatorship while ultra-conservative Vox party won 12 seats.
