An influential Brexit expert at the European Parliament says the legislature might even meet in an extraordinary plenary next week if that is what is needed to push the Brexit deal through.

The EU parliament is awaiting approval for the Brexit deal in the House of Commons, which could come in the next hours or days. After that, the EU could move speedily.

Greens lawmaker Philippe Lamberts said Monday that "we could ratify next week, if not this one."

He added the Brexit deal could also spill into November, beyond the current Oct. 31 deadline for Britain to leave the EU.

British Prime Minister Boris Johnson has already asked for a Brexit extension even though he is still trying to get out of the EU by the end of the month.
