Following the first round of withdrawal negotiations, the UK and the EU adopted a common approach to the financial regime in the December 2017 Joint Report. The comparison defines the financial commitments covered, the methodology for calculating the UK share and the payment plan. The Withdrawal Agreement transforms the approach set out in this report into a legal text and provides for further negotiations on the UK`s contributions to the EU budget in the event of an extension of the transition period. An extension would not affect financial management, which would continue as agreed. Immediately after the announcement of a revised withdrawal agreement on 17 October 2019, Labour, the Liberal Democrats and the DUP said they could not support the new agreement.  The new relationship between the EU and the UK begins once an agreement has been reached and approved by the EU Member States, the European Parliament and the UK Parliament. On 15 November 2018, a day after the agreement was presented and supported by the Cabinet of the British government, several members of the government resigned, including Dominic Raab, Secretary of State for Exiting the European Union.  Under the backstop, the UK will establish a customs union with the EU (with the exception of trade in fishery and aquaculture products, which is expected to be the subject of a new agreement on fishing opportunities by 1 July 2020). The Brexit deal will only come into force once the Brexit law has been passed by the UK Parliament. The new relationship will only be clear when negotiations are completed, at the end of the transition period. The new agreements will enter into force after the transitional period ending on 31 December 2020. . .
