David Cameron has said the UK will not pay an additional £1.7billion (€2.1billion) demanded by the European Union after a recalculation by the European Commission about how the economies of member states have performed since 1995.

Paying the additional sum would add about a fifth of the UK's current annual contribution to the EU, while under a leaked European Commission document Germany would receive a £614million rebate and France £788.7million.

The above chart from Statista shows how UK contributions to the EU have changed over the last decade.

The graph below meanwhile puts the UK contributions into context. The figures relate to the 2013 budget.
