Wrong Carter, what you started as being the case would amount to restraint of trade. Illegal within the EU as part of free movement. What jurisdiction applies to a commercial contract depends entirely on where that contract is signed. That great screed that Shaw pasted would apply to any worker signing up with a British employer with the contract signed in the U.K.

Oh just to clarify things for you, Cameron and the "pig thing" - it never happened - sorry to piss on your fireworks. If you doubt it you could always waste your time and energy by trying to find some substantive evidence that it did. So far many with far greater and better resources and contacts than you have tried and failed.
