One must remember that a direct quote from Boris Johnson, the (now) prime minister was "Fuck Business". Leaving the EU is about avoiding scrutiny, not stimulating business.
While it's true that the Tory party of old (charitably until ~2015) may have cared about competitiveness for business, that party is now dead - overtaken by the extreme right. The only thing that matters to them at this stage is power, and personal enrichment, and they have become masters of disinformation and confusion to ensure it -- a job made much easier by the generally awful state of the press in the UK. It's a shame that the opposition are, as you say, no better.
