Spain's Socialist Party chief resigns: advisor

The embattled head of the Spanish Socialists Pedro Sanchez announced his resignation after losing a vote among top party members summoned for a showdown on Saturday, an advisor and an opponent said.

Sanchez's opponents want to see the opposition party lift its veto on a new government led by acting conservative Prime Minister Mariano Rajoy, which could be key to unblocking Spain's nine-month political paralysis.
