Britain’s Brexit bill could increase after leaving the EU because of its soaring liabilities.
A report released yesterday revealed the bloc’s spending promises and pension costs surged by tens of billions last year.
It means Britain may be required to contribute more money than expected to the EU budget under an agreement struck in March.
The UK has committed itself to honour liabilities racked up by the EU until the end of 2020. This is estimated at £39billion, to be met by payments spread until 2064.
But the European Court of Auditors’ annual report said the EU’s pension liabilities have grown by more than £12billion in a year.
A UK Treasury spokesman said: ‘The UK cannot be made to pay for additional spending beyond what it has signed up to as a member.’
