The European Parliament is expected to approve any trade deal and the chairman of the largest legislative group has said that any deal with EU lawmakers would have no chance if the UK only complied with the smallest paragraph of the Brexit deal. On 15 November 2018, the day after the agreement and the support of the British government were presented, several members of the government resigned, including Dominic Raab, Secretary of State for leaving the European Union.  The withdrawal agreement provides for a transitional period until 31 December 2020, during which time the United Kingdom will remain in the internal market to ensure the flow of trade until a long-term relationship is concluded. If no agreement is reached by then, the UK will leave the single market without a trade deal on 1 January 2021. The withdrawal agreement is closely linked to a non-binding political declaration on future relations between the EU and the UK. The Irish backstop is withdrawn and replaced by a new protocol on Northern Ireland/Republic of Ireland. The whole of the United Kingdom comes from the EU Customs Union as a single customs territory, with Northern Ireland included in all future UK trade agreements. However, Northern Ireland adopts EU internal market rules for goods (including EU VAT) in order to avoid a hard border and remains an access point to the EU customs union.  The result is a de jure customs border on the island of Ireland, but a de facto customs border in the Irish Sea. EU tariffs (which depend on a free trade agreement between the UK and the EU), levied by the UK on behalf of the EU, would be levied on goods that leave Britain for Northern Ireland and are “threatened” and then transported and sold to the Republic of Ireland; If this is ultimately not the case, companies in Northern Ireland can apply for discounts on products for which the UK had lower tariffs than the EU.
  “It makes no sense to negotiate a future deal (with) a British prime minister who throws out the window the agreement he himself signed,” said Manfred Weber of the centre-right Party of the European People`s Party. The agreement covers issues such as money, citizens` rights, border agreements and dispute resolution. It also includes a transition period and an overview of the future relationship between the UK and the EU.
