As an accounting practitioner I've seen a few divorces in my time, and how people prepare for them, consciously or not. They began to steel themselves for life alone; contingency plans made; new alliances are tested, budgets are thought through. Only then do they leave. Passion often follows the testing, and does not precede it.
In that case I read this with interest in the FT this morning:
EU officials have begun work on a plan to create a long-term budget without the UK in a move that reflects mounting frustration that Britain’s demand for a spending freeze cannot be reconciled with the rest of the bloc.
Both EU officials and national diplomats have been studying the legal and technical feasibility of devising such a budget, according to people familiar with the discussions, ahead of a two-day summit beginning on Thursday in Brussels, where the EU’s 27 heads of government will try to reach an agreement on the long-term budget.
