I see that May is being conciliatory over Gibraltar, so I reckon she can see a way forward. EU regulations are incorporated into British law, so she can boast that all laws are British, while in fact, companies are shadowing EU regs, (they have no choice). Immigration will be allowed in certain sectors, and all the bluffs and threats (Gibraltar, cooperation over security, the EU bill, EU citizens), will be smoothed over. Her big problem might be the headbangers, but she will hope to seduce them with lots of rhetoric about glorious global Britain, and anyway, many of them are brain-dead. But remember Murphy's law.
