Emmanuel Gregoire, a Socialist little known to the French public, has been elected as mayor of Paris in a run-off vote, succeeding fellow party member Anne Hidalgo.

Soon after claiming victory, Mr Gregoire, 48, took a city bike through the streets of Paris toward City Hall, echoing his promise to make the French capital greener.
