 France is in a state of upheaval after the far right performed strongly in the first round of parliamentary elections. The BBC's Mark Lowen is in Paris. President Macron came to power here pledging to revive the political centre, to bridge right and left. What he's actually done and what has happened under his watch is to polarise and push people into the extremes of right and left. There will be a lot of people who will be furious at President Macron for a gamble that has misfired.
