As a Brit I can not associate a single positive outcome to us leaving the EU. Not saying one doesn't exist but to me, personally, I can't. Many probably feel this way so they blame all the big issues we have like prices and immigration on Brexit. Is there direct causation here? Not sure, maybe. Either way I suspect we will end up joining again just might take a decade or two.
Edit: one positive this year was us becoming part of the Horizon programme.
