Britain’s Queen Elizabeth granted royal assent to the UK’s Brexit legislation on Tuesday, ending months of debate over the legislation that will formally end the country’s European Union membership.

The announcement was made by House of Commons speaker John Bercow.

“I have to notify the House in accordance with the Royal Assent Act 1967 that her Majesty has signified her royal assent to the following acts … European Union Withdrawal Act 2018,” Commons Speaker John Bercow told lawmakers during a session of the house, according to Reuters.

Eurosceptics celebrated the passing of the bill through Parliament last week as proof that, despite continuing uncertainty in the negotiations with Brussels, Brexit was happening.

“Lest anyone is in any doubt, the chances of Britain not leaving the EU are now zero,” International Trade Minister Liam Fox said.

In UK law, after a bill has passed through the House of Commons and House of Lords it becomes an Act of Parliament once it is granted royal assent by the sovereign.
