I cannot imagine a deal which will be acceptable to both the EU and the British people (not including the snowflakes who post on here claiming the end of the world is nigh) so it's very unlikely.
We do not need a deal and will be far better off just leaving, keeping the £39bn bribe, no Withdrawal Agreement (not necessary and will only work to our disadvantage) and move to trade on WTO terms. Our amended schedules for this (proposing splits in trade quotas which were originally EU28 into EU27 & UK) despite nonsense in the remainer media, are in negotiation and will be fine.
The EU is not strong enough to take on global financial markets. The world finance capitals are jointly London and New York. Frankfurt doesn't make the top 20 and Paris doesn't appear on the list at all.
The 'investigation' into Leave.UK - which wasn't even the official Leave campaign, Vote Leave was - is a transparent witch hunt with no merit. It was, in fact, the remain campaign which broke funding rules, not Leave. Even in the unlikely event of Banks being found to have committed some impropriety, it would not affect the referendum result and to think it could is grasping at straws. Why can't you people admit defeat - it's well over 2 years - and reconcile yourselves to leaving? Join us in the reality based community at your convenience.
Focus on this. Brexit is not and never was about money. It is about sovereignty, about the UK becoming a self-governing democracy again, not a province of a corrupt, anti-democratic German Empire, which is where we are currently headed.
