the UK has control over that You have to remember that a key part of the reason Leave won is that British people don't trust their leaders to be honest or consistent on the topic of the EU. Politicians across Europe, not just the UK, have a long established track record of promising voters they'll reject further integration or power transfers to Brussels and then turning around and doing exactly that. As the Brexit referendum has helpfully revealed this is because the civil service and many MPs don't actually believe anyone should be allowed to vote against the EU and are busy trying to block implementation of leaving. Given that, the fact that the UK could theoretically veto Turkey's membership is irrelevant. Politicians can't be trusted to use it. Leaving completely is the only sure way to stop them doing whatever Brussels asks for.
