Question to the HM Treasury:

To ask Her Majesty's Government whether the share of pension liabilities to which they have agreed as part of the UK's departure from the EU is based on (1) the full budget share of those liabilities, or (2) the number of British staff employed by the EU up to and until exit day.

As set out in the Withdrawal Agreement, as part of the Financial Settlement, the United Kingdom shall be liable to the Union for its share of the financing of the Union's liabilities incurred until 31 December 2020, including pensions. The UK’s share, as set out under Article 139, shall be a percentage calculated as the ratio between the EU Budget contributions made available by the United Kingdom in the years 2014 to 2020 and those EU Budget contributions made available during that period by all Member States and the United Kingdom. The Office for Budget Responsibility in October 2018, estimated the UK’s share of the EU’s pension liabilities as set out in the Withdrawal Agreement, at €9.75 billion.
