Jean-Luc Melenchon announces 2017 France presidency bid
The French left-wing politician Jean-Luc Melenchon has announced he will stand for president in spring 2017.
Mr Melenchon, of the Left party (PG - Parti de Gauche), said the means of production, trade and consumption must be changed, and cited climate change as one of his concerns.
He said: "This is a tremendous opportunity to loose the bonds that paralyse us today."
Mr Melenchon made an unsuccessful bid for the French presidency in 2012.
He received 11% of the votes, putting him in fourth place.
He is a former senator and currently serves as an MEP.
The current president, the Socialist Party's Francoise Hollande, has not yet confirmed whether he will seek a second term.
It is expected that Marine Le Pen of the National Front will run.
