Queen Elizabeth II gave her formal assent on January 23 for Britain to end its decades-long involvement in the European Union and seek a more independent but uncertain future at the end of the month.
The head of state’s ceremonial approval of the withdrawal legislation allows Britain to leave its closest neighbours and trading partners after years of bickering and three delays.
Two top EU officials in Brussels are expected to sign the separation treaty on Friday and Prime Minister Boris Johnson — the pro-Brexit figurehead of Britain’s seismic 2016 referendum — will put his name on it in the coming days.
“At times it felt like we would never cross the Brexit finish line, but we’ve done it,” Johnson said after both houses of the British parliament ratified the withdrawal bill on Wednesday.
“Now we can put the rancour and division of the past three years behind us and focus on delivering a bright, exciting future.”
The January 31 split caps a remarkable political comeback for Johnson at one of the most difficult points in Britain’s post-war history.
He quit former prime minister Theresa May’s government in 2018 in protest at what he viewed as her pro-European separation terms.
Johnson returned as May’s successor in July last year and has since managed to negotiate his own deal with Brussels and regain the government’s control of parliament in a risky early election last month.
The rest was a formality. Lawmakers barely debated the withdrawal agreement before passing it — even though critics called it worse for Britain than the one reached by May.
Johnson will celebrate his victory by issuing commemorative coins and chairing a special cabinet meeting in England’s pro-Brexit north on January 31.
Johnson will now be responsible for defining the terms on which Britain trades and shares everything from data to fishing waters with the remaining 27 EU member states.
The formal talks are not expected to begin until March but the war of words is already intense.
Johnson rejects EU arguments that the end-of-year negotiations deadline is too short to reach a comprehensive deal.
The UK government is also demanding the post-Brexit right to set its own rules on politically sensitive issues such as environmental standards and workers’ rights.
EU officials say this will give Britain an unfair advantage and are threatening to retaliate with tariffs and quotas that could hit the UK auto and pharmaceutical industries especially hard.
European Central Bank chief Christine Lagarde said the bloc’s financial system was ready for the next stage.
