The Chequers plan, officially known as The future relationship between the United Kingdom and the European Union (Cm 9593), was a UK Government white paper concerning Brexit, published on 12 July 2018 by the prime minister, Theresa May.

[7] Continued access to the European Single Market for goods and a common rulebook on state aid would be agreed, preventing either side from subsidising their own industries.

For its part, the UK would commit to maintaining high environmental, climate change, social, employment and consumer protection standards.

[13] This policy was explicitly rejected in September 2018, the EU's chief Brexit negotiator, Michel Barnier, said that the integrity of the European Single Market was "not negotiable", and that there can be no "cherry picking" of the market's four freedoms: free movement of people, goods, services and capital.

[7] This had been rejected by the President of the European Council (Donald Tusk) and Barnier before it was in the Chequers deal, as well as on numerous dates from 20 July to 21 September 2018.

[21] In November 2018, the Brexit negotiations concluded with a Withdrawal Agreement and a Political Declaration; this included a "commitment to frictionless trade in goods through a common rulebook, the centrepiece of the Chequers plan.

Leader of the Opposition, Labour Party's Jeremy Corbyn, described the political declaration as "26 pages of waffle".
