French President Emmanuel Macron says the withdrawal deal on Brexit cannot be renegotiated and that it’s now up to the British Parliament to make the next move.

Macron spoke Friday after an EU summit and a one-on-one meeting with British Prime Minister Theresa May, seeking help from EU leaders to help her sell the deal to skeptical lawmakers.

Macron insisted “there is one accord, the only one possible,” adding “we cannot renegotiate it.” He told reporters that now it’s “the British parliament’s time” to decide whether to accept or reject it.

He said EU leaders are willing to “clarify and discuss” the accord, and said EU leaders at the summit sought to debunk “fantasies” about the so-called backstop for the Irish border.

Romania’s president is stressing how important it is for Romanians and other European Union citizens in the U.K. to have their rights respected after it leaves bloc.

In a meeting with British Prime Minister Theresa May in Brussels, Romanian President Klaus Iohannis said the divorce deal was “important... to guarantee the rights of (Romanians) who live, work or study in Britain.”

Iohannis said all EU citizens living in the U.K. should be treated in a non-discriminatory way, both those currently there and those who move there in the future.

Romania takes over the rotating presidency of the EU on Jan. 1. Britain’s departure from the bloc, scheduled for March 29, occurs on its watch.
