Its only stage one of a long negotiation. Cameron has done the right thing and, as he said, we are not Eurosceptic but we are defending Britain's interests. It could well be that Merkel and Sarkosy will be back to garner the UK's support, Merkel in particular needing the stricter monetary and budget control support that the UK would back her on, as well as holding onto her position about the debt/GDP benchmarks that will have to be negotiated.
The concession, the exemption of London to be regulated more by the UK Government.
The second stage of "delicate negotiations" and support also will include those countries who are on the wrong side of the ratio line - Greece and Ireland for starters, Italy? Portugal? Spain? If it is set at 3% of budget deficit as currently proposed, well that includes the likes of the Neths, Slovakia, Slovenia, Austria, and France. 5% would include the suspects plus France and even ourselves.....

It would not surprise me if we see a very different position for the Uk from today's position by, say, end Q1
The other thing - 3.5 months is a hell of a long time in economics and re the EU debt problem - the house of cards could well fall before that - a run on Spain or France peut-etre. At that point, DC being on the fence may be the best position for the UK.....
