Spanish opposition parties have launched a fierce campaign to end the conservative government of Mariano Rajoy after courts ruled that his Partido Popular profited from a large kickbacks-for-contracts scheme. The Socialist opposition announced a vote of no confidence against the prime minister with the backing of anti-establishment and left-wing parties, while the pro-business Ciudadanos (Citizens) – which had supported the conservative minority government until now – urged Mr Rajoy to call a fresh election.
