Boris Johnson has said the UK has "crossed the Brexit finish line" after Parliament passed legislation implementing the withdrawal deal.
The EU Bill, which paves the way for the country to leave the bloc on 31 January, is now awaiting royal assent.
The PM said the UK could now "move forwards as one" and put "years of rancour and division behind it".
The EU's top officials are expected to sign the agreement in the coming days, while MEPs will vote on it next week.
The European Parliament will meet on 29 January to debate the agreement, which sets out the terms of the UK's "divorce" settlement with the EU, the rights of EU nationals resident in the UK and British expats on the continent and arrangements for Northern Ireland.
Its ratification is expected to prove a formality.
