The British House of Commons passed an important law amendment on Saturday with a majority of sixteen votes, which forces Prime Minister Boris Johnson to request a Brexit postponement, even though his deal is accepted. In response, the government postponed the vote on its agreement.

The Letwin amendment was introduced as a kind of insurance policy and requires that all legislation necessary to implement the exit agreement must be passed before the deal can be approved.

To leave the EU, the UK must not only approve a Brexit deal, but the government must also ratify the deal.

The parliamentarians who voted in favor of the change were afraid that the hardliners from the Conservative party would still be hampered by ratification if the deal was accepted at the Lower House. If they did not sign in the end, the UK could still crash out of the EU without agreement on 31 October. The Letwin amendment therefore ensures that everything must first be regulated by law.

Johnson is expected to present the necessary legislation to parliament on Monday. He thereby meets the Letwin amendment. Then the prime minister will probably resubmit his deal to the lower house on Tuesday. The chance that he will then find a majority will increase.
