Europe expects the UK to pay an extra £1.7bn towards the EU budget “and that’s that”, a vice president of the European Parliament has said.
Alexander Graf Lambsdorff, a German MEP, said the EU would be “exasperated” if the UK tried to avoid payment.
On Friday David Cameron said the EU had “another think coming” if it thought Britain would pay the bill by the 1 December deadline.
The EU demanded the extra amount because of growth in the UK economy.
Mr Lambsdorff told the Today programme on BBC Radio 4 that “everybody has to pay their dues”.
