Whenever EU reform and renegotiation are being debated, one of the most powerful claims made by the status-quo side is that it would generate uncertainty which would be bad for business.

Well today’s FT reports that according to a survey of one in three FTSE100 chairmen conducted by Korn Ferry, a leadership and talent consultancy, the overwhelming majority – 81% – said the want to see the UK renegotiate its relationship with the EU. In comparison, only 15% back staying in no matter what and 4% supporting an outright exit. There was naturally a range of views in terms of how far-reaching the renegotiation ought to be; some business leaders backed only “limited” changes, but a clear majority – 63% – backed “a return of social and economic power to nation states”.
