Spain's king picks socialist chief to try to form government
Speaking after a brief meeting with the king, Lopez said Sanchez would need at least three weeks, possibly a month, before a first parliamentary confidence vote can be organised.
Under Spain's constitution, a two-month deadline for the formation of a government comes into effect once this first vote takes place. If that deadline expires a new national election is called.
