Jean-Luc Melenchon, member of the French far-left Parti de Gauche, speaks to the media as he attends a demonstration against austerity plans which affect salaries and pensions in Paris, April 9, 2015. French unions sought on Thursday to ramp up protests against public spending cuts, calling for work stoppages and marches by public-sector staff that coincided with strikes by air traffic controllers and state radio workers.
