National Security Adviser John R. Bolton told British Prime Minister Boris Johnson that President Trump wants Britain to leave the European Union successfully.  A no-deal Brexit could also have offered a possible change in the UK`s alignment with US rules and not EU rules.  Prior to the conclusion of last year`s Withdrawal Agreement, the UK and the EU confirmed their intention to allow flights to continue in a no-deal scenario, which gave passengers and cargo operators security and confidence at the time. The Withdrawal Agreement provides for a transition period until 31 December 2020, during which the UK will remain in the Single Market to ensure smooth trade until a long-term relationship is agreed. If no agreement is reached by that date, the UK will enter the single market on the 1st. January 2021 without a trade agreement. A non-binding political declaration on the future relationship between the EU and the UK is closely linked to the Withdrawal Agreement. As the scheduled Brexit date approaches in spring 2019, the Department for Exit from the European Union (DExEU) and the Civil Contingencies Secretariat have developed preparedness and contingency plans for the possibility of a no-deal Brexit, codenamed Operation Yellowhammer – the emergency coordination plan.  In August 2019, it was reported that the Cabinet Office “could not confirm” that Operation Yellowhammer would remain available for a Brexit in the fall.  On August 18, 2019, a leak revealed that the policy still exists and is being updated.   Receipt of the agreement in the House of Commons ranged from cold to hostile and the vote was delayed by more than a month. Prime Minister May won a no-confidence motion against her own party, but the EU refused to accept further changes.
