If an agreement is reached it will need to be turned into legal text and translated into all EU languages, then ratified by the European Parliament. The UK government is likely to introduce legislation implementing parts of any deal reached, which MPs will be able to vote on. And the 27 EU national parliaments could also need to ratify an agreement – depending on the actual contents of the deal. But before that, there are even more hurdles to overcome. After the talks between the teams on Sunday and the further leaders’ call on Monday, the UK Internal Market Bill will return to the Commons. Certain clauses allow the government to override elements of the original treaty with the EU for Brexit – the withdrawal agreement – which, if implemented, would break international law. The EU are unhappy with it, as are the House of Lords, who voted to scrap those clauses of the bill. But the government is still backing its measures, which could cause tensions in the trade talks, and they are expected to push them through on Monday night. Another bill with similar provisions – the Taxation (Post-Transition Period) Bill – will also return to the Commons this week. In addition, EU leaders will be meeting in Brussels on Thursday.
