That makes sense. This is going to be a clean break. It doesn't need to be an acrimonious one - unless the EU wants it to be.
The UK is committed to trade relations - including making a new deal with the EU.
I might personally hope for Theresa May to say something like. "I hope the EU breaks apart, and that Martin Schultz dies in a fire", but I can see how that would be impolitic :0)
I had to break away, so I don’t know if she’s actually said anything substantive yet....
