"I refuse this nomination because I do not think it is the government's role to decide who is honourable," Piketty told AFP.

"They would do better to concentrate on reviving (economic) growth in France and Europe," added Piketty, who was once close to the Socialist Party but has distanced himself from the policies of President Francois Hollande.
