French far-right presidential contender Marine Le Pen has called for more food to be produced and consumed in the country. Le Pen, visiting the Rungis wholesale market outside Paris on Tuesday, said the French government must promote meat from France. She says: "Let's promote the 'eating French' especially in (school) canteens where our children must take advantage of healthy, quality products." Le Pen was booed by some workers in the fruits and vegetables section. The National Front leader is facing pro-European centrist Emmanuel Macron in the May 7 presidential runoff.
