I wonder if later today when No Deal is announced will Ursula von der Leyen also announce her resignation because of her colossal and possibly catastrophic failure to agree a mutually beneficial trade deal with the UK. A deal which has been said should have been the easiest in history. 
I guess being unelected by and totally unaccountable to the people of the member states of the EU, that'll be no then... 
And why would she do that?
Or are you still under some misapprehension that the EU would have rolled over and let us have our cake and eat it? Or that £350m a week is going to the NHS as per the bus?
Sorry to let you into a secret, the leavers lied. Knowingly. It was obvious at the time that the EU weren't going to agree with God Farage's wishes.
And as New POD says, its turned out exactly as predicted, and UK industry has lost its biggest market, so is pretty much donald ducked. Which obviously has huge knock-ons to the rest of the economy. This is being felt first in the retail industry, which never had time to recover from the 2008 crash before Brexit came along and finished it off. Passionate leave supporters could argue that batflu is a cause, but that hasn't even had any real impact to things yet - every retail business thats gone tits up was going tits up before this sniffle came along.
You mistakenly believe that this is about the economy and trade, but if it was they'd have wrapped up a mutually beneficial deal at the end of June, the first deadline.

This is about politics, not economics and as Liam Fox said this should have been the easiest deal in history. It's worth noting that Liz Truss's Department for International Trade have signed over 50 FTA's so far which is unprecedented for any country. So much for the little speck in the North Sea and it shows what can be achieved between two friendly countries pursuing a common goal.

It's also worth noting that Britain is not the first major economy that the EU has tried and failed to achieve an FTA with, the USA, India, the Gulf states...
While there's little point in rehashing the arguments of 2016, I can assure you that as soon as David Cameron announced the referendum, I knew how I was going to vote, and I'd be willing to bet my mortgages that the vast majority of leave voters did too. What was written on the side of a bus or what Nigel Farage came out with was pretty much irrelevant, because there was a deep seated uneasiness across the country that power was slipping away from our democratically elected parliament (well half of it..) to the unelected and unaccountable commissars in Brussels. That's all.
As to VDL and whether she should resign or not, surely the whole point of the EU is to make people's lives better, not worse? An FTA with the worlds 5/6th biggest economy on their doorstep who by and large follows the same principles should have been high on her list of priorities, and could have been achieved in a friendly and speedy manner. Instead they decided to go down the road of constraining the UK driven by a vindictive desire of punishment, so yes I think she should resign if there's no deal as it's a colossal failure for the EU and she is the leader.

As you say, she won't. Why should she?
