Spain's acting Prime Minister Pedro Sanchez said today he is not planning to call a new election amid complicated, multi-party talks ahead of a vote on his investiture at parliamentary sessions on July 22-23.

"I'm not contemplating, and am not working on the assumption of, another election," Sanchez said during an interview with national television.

Talks have stalled amongst political parties over forming a government after the election on April 28 in which Sanchez's Socialists party (PSOE) won without a parliamentary majority.
