The "problem" of EU bureaucracy is not the number of people working in Brussels. It's the requirement to comply with EU law. I am personally very familiar with EU law on public sector procurement - the famous "OJEU" regulations.
And the problem there is not actually the regulations - it's the way people apply them. Like H&S, the issue is over-officious idiots wilfully misinterpreting the rules to make themselves feel important. The actual rules are pretty sensible and helpful.
If you took the rules away, you'd still be left with the idiots.
I believe its called " gold plating" where perfectly sensible and proportionate EU directives, regs etc are implemented in the UK with an added layer of complexity, strictness and " stupidity." In the days before the Official Journal, the CCTA used to procure IT systems on behalf of govt departments. Trust me, the OJ rules as it were , are infinitely preferable!
It seems, though, that UK govts of any leaning are ineffective in getting the machinery of govt to stop gold plating.
