BRUSSELS, March 12. /TASS/. Brussels and London have agreed to legally binding guarantees on the Brexit agreement and Irish backstop, European Commission President Jean-Claude Juncker said after a meeting with UK Prime Minister Theresa May in Strasbourg.

"Our agreement provides meaningful clarifications and legal guarantees to the Withdrawal Agreement and backstop. The choice is clear: it is this deal, or Brexit may not happen at all," Juncker said.

"Let's bring the UK's withdrawal to an orderly end. We owe it to history," he added.
