The House of Lords of the British Parliament ratified the deal on January 22, after the House of Commons passed it.
"We promised to #GetBrexitDone and we are on track to leave on 31st January," Steven Barclay, the British Secretary of State for Exiting the European Union posted that on Twitter.
The procedure is supposed to be over on January 31.
On January 20, the UK House of Commons backed Prime Minister Boris Johnson's plan for the UK to leave the EU on January 31. MP voted 358 to 234 - a majority of 124 - in favor of the EU (Withdrawal Agreement) Bill, which now goes on to further scrutiny in Parliament. Speaking on the results of the voting, Johnson said that the country was now "one step closer to getting Brexit done". It is worth noting that Johnson, in his turn, insists that a trade deal with the EU can be in place by the end of the transition period. However, critics say this timescale is unrealistic.
