Britain is concerned about the possible impact of a reorganisation which could marginalise its influence in the EU.
The two leaders will discuss plans to reorganise the governance of the eurozone which will see closer co-operation within the 17-strong bloc, potentially lessening Britain's influence.
The move will be considered by the European Council at the end of next week, but Germany and France will agree a plan of action on Monday.
Any reforms of the Maastricht Treaty rules governing the eurozone will have to be agreed by all 27 members of the European Union.

Downing Street said it was waiting to see the options paper for reform which European Council president Herman van Rompuy is drawing up for next week's gathering of EU heads.
