PARIS (Reuters) - France's 2022 presidential election is Emmanuel Macron's to lose. All opinion polls show the incumbent president reaching the second round and winning re-election.

However, after a first term mired in social unrest - during which he took steps to liberalise France's labour laws, cut taxes on the wealthy and businesses and tried to reconfigure trans-Atlantic relations - the margins are tighter than the drubbing he delivered to the far right's Marine Le pen in 2017.
