The two leaders acknowledged they recently had a strained relationship, after Mr Cameron refused to let Britain bind its finances closer to other European countries in the treaty. It was reported that Mr Sarkozy had called the Prime Minister an “obstinate kid” over Britain’s refusal to share taxation and spending policy with the rest of Europe. However both leaders were yesterday anxious to underline they are “friends” as well as colleagues and have got to know each other better since their disputes.
