The ex-Brexit negotiator said anger is boiling up across his country over red tape and unchecked immigration.

He said it was causing “social unrest or anger”.
And he warned the EU is doomed if it fails to learn lessons from Brexit.

Mr Barnier, said to want to become the French president, added: “Let’s ask ourselves why 52 per cent of citizens voted against Brussels.

“There are reasons we can find — not just in the UK but here in France — citizens who want to leave the EU.

“It’s important to listen to the anger in the UK.”
