Reuters reports that EU lawmakers kicked off a last debate on Tuesday on the post-Brexit trade agreement between the European Union and Britain, ahead of a vote that is expected to give the accord overwhelming approval.

That vote will be the final step towards ratification of the EU-UK trade and cooperation agreement, struck in December after more than four years of acrimonious negotiations and lingering mistrust as Britain ended 47 years of EU membership.

The accord crafted in the last days of 2020 only entered force on a provisional basis until the end of April, pending approval from the European Parliament. Lawmakers will vote late on Tuesday, with the outcome made public on Wednesday morning.

There is no doubt that they will back the deal, after assembly committees earlier cleared it by 108 votes to 1. If they did not, EU-UK ties would fall back to basic World Trade Organization terms, with quotas and tariffs.
