EU Brexit negotiator Michel Barnier makes controversial immigration proposals

Michel Barnier, who gained fame across Europe as the EU's lead negotiator in the Brexit process, has caused controversy by suggesting France should be able to opt out of some of the bloc's court rulings.
"On immigration, we must regain our legal sovereignty to no longer be subject to the judgments of the ECJ or the ECHR. We will propose a referendum in September  on the question of immigration," he said at a campaign event in Nimes.
Barnier is campaigning to be the next president of France in next April's election.
He has called for a "constitutional shield," with the aim of ensuring French national legislation is seen as more important than European laws.
