Puente's move six days after this year's second traumatic rail accident has left the ruling Socialists fighting an election campaign without one of their most combative, but also polarising, voices.

In a brief televised address, Sanchez praised Puente for his political dignity, saying his decision helped the country regain confidence in the rail system.
