Re: Really ....
"We cannot renegociate a deal with just Germany for their cars"
Germany will still be able to sell the UK cars (if we have the money). The terms on which they're sold here will depend on those set by the UK government.
The problem is negotiating the terms on which to sell our cars in the EU. Those terms will be set by the EU of which we won't be a member. What was that about control?
And it's been made quite clear that the existing terms won't be applied unless we agree to free movement of people. Wasn't free movement one of those things Brexiteers wanted to see the end of?
