Question to the HM Treasury:

To ask the Chancellor of the Exchequer, what estimate the Government has made of the annual amount it is prepared to pay for each level of access to the EU single market.

As set out in the Government’s analysis of the economic and fiscal impact of EU exit (below), the terms of any future financial contributions to the EU related to our future relationship will be a matter for negotiation. However, the Government has been clear on the areas where future spending may be incurred, should the UK and the EU agree. The Political Declaration, published on 25 November, sets out that the UK and EU will “make a fair and appropriate financial contribution” in return for “participation in Union programmes… in areas such as science and innovation, youth, culture and education, overseas development and external action, defence capabilities, civil protection and space.”
