David Cameron has said new treaties on defence and nuclear co-operation with France marked a "new chapter" in a long history of defence cooperation.Speaking alongside French President Nicolas Sarkozy, the UK PM said it would make both countries' citizens safer and would save money.
A centre will be set up in the UK to develop nuclear testing technology and another in France to carry it out.
The leaders also confirmed plans for a joint army expeditionary force.
After both leaders signed the two treaties, Mr Cameron said: "Today we open a new chapter in a long history of co-operation on defence and security between Britain and France."
