Brexit - impact on London as international choice for disputes

In a letter to the Gazette, the president of the Paris Commercial Court claims Brexiters ‘underplay or seek to ignore’ the fact that from next March, judgments by the London Commercial Court will no longer enjoy automatic enforceability in EU member states. 

Is it inevitable that where EU parties may have chosen English law and English jurisdiction for disputes, they will be less likely to do so after Brexit? Only time will tell.

However, as noted in City A.M yesterday, this issue extends further to other international commercial parties and jurisdictions  - will such parties be more likely to choose alternative jurisdictions post Brexit? And will legal advisers advice be to do so?  Currently, many big commercial parties often elect to have Arbitration clauses over litigation, so they may still choose/be advised to choose English law to govern agreements, but go elsewhere to resolve disputes to save costs and overcome potential enforceability obstacles.
