Spain's labour minister steps down following election resultsSpain's labour minister and one of the country's three deputy prime ministers, Yolanda Diaz, has announced she is stepping down as leader of the left-wing Sumar alliance following its poor showing in the European elections.Sumar, which was brought together last year to help fend off the far-right during Spain's general election, won only three seats. The United Left coalition - one of Sumar's core members - failed to gain a single seat.As a result, Ms Diaz has decided to step down as Sumar coordinator, though she will continue with her ministerial duties.
