DUBLIN -- The coming week of Brexit talks represents "the moment of truth" and will require Britain "to put all of its cards on the table," European Council President Charles Michel said Thursday.

Standing beside Irish Prime Minister Micheál Martin following talks in Dublin, Michel said peace on the island of Ireland and the integrity of the EU's single market were at stake.

"The EU stands in full solidarity with Ireland. And this is especially true when it comes to the full implementation of the Withdrawal Agreement and the protocol on Ireland and Northern Ireland," Michel said.

"This text has been negotiated for three years. Each word, each comma has been debated for hours and hours. It has been ratified by both parties. There is simply no question on its full implementation. This is a matter of law, a matter of trust," he said.
