I don't tell you how to build aircraft so don't tell us how to run our country.
The EU is not the single market so the functioning of Airbus is not in any way affected by the UK leaving the EU. Most of the rules of the single market are made by global bodies. This you know full well. The same is true of the regulations with which you must comply.
To say you would reconsider investment in the UK in the event of Britain leaving the European Union ignores the fact that you already have, some time ago - not least by ending 100 years of aviation at Filton by closing the runway. This does not suggest to me a long term commitment to the UK.
Moreover, the repair jobs based at Bristol have been gradually outsourced to India over the last few years so please don't pretend you care about British jobs. We know that first and foremost you are a French company and you have been gradually pulling out for years, placing all the best jobs in Toulouse.
If it's labour costs that bother you, you should be glad we're leaving the EU. As to jobs, don't forget those jobs are heavily subsidised with OUR money. We CAN take our money elsewhere.
Meanwhile, our order for the A400M is worth less to us than the maintenance contracts for the C130. We can survive without it. And while we're on that subject, rather than pontificating on how we should run our democracy, how about you concentrate on making the A400M not fall out of the sky killing all the crew - since our RAF men and women will be serving on them?
That's your business. Who governs us is not.
