Britain will have the option to reverse Brexit, European Union lawmakers are set to announce.
The European Parliament is drafting a resolution as a response to Theresa May triggering Article 50 and beginning the formal process of exiting the EU.
The resolution will provide the UK with an option to halt the Brexit proceedings as long as other members agree.
"We do not want to close the door to common sense," said Philippe Lamberts, Belgian co-leader of the Greens in the parliament.
“There will be a reference to the revocability of Article 50."
Donald Tusk, the European Council President, said he was sure the other member states would support Britain if it had a change of heart.
"If we have a chance to reverse this negative process, we will find allies," Mr Tusk said.
He is not expected to mention the resolution when he gives the EU's response to Ms May triggering Article 50 and will instead issue draft guidelines for the Brexit negotiations, according to EU officials.
The EU’s chief negotiator, Michel Barnier, has discouraged politicians from making explicit reference to stopping Brexit in the resolution, parliamentary officials said.
He has reportedly insisted that any plans must include a reference to requiring the unanimous approval of all 27 member states.
Aides to Mr Barnier declined to comment.
