Rapid change may not be possible but you can signal your intent without blowing things up; but the current Labour leadership simply don't seem to be interested in really tackling the issues whether that's through timidity or not giving a toss I don't know but the effect is the same.
Here's a small but telling example: in 2025 Marcus Bokkerink was forced to resign by the Government as chair of the CMA, predominantly because in their eyes he wasn't 'pro-growth' enough, his vision for growth was through making markets properly competitive which seems not unreasonable for the head of the competition authority. But that wasn't 'business friendly' enough for the government so he was replaced, supposedly temporarily, by Douglas Gurr the ex head of Amazon UK (that well known champion of competition). Fast forward to the CMAs review of the veterinary industry and instead of actually dealing with the fact that half a dozen private equity firms are hoovering up the entire industry and price gouging (and thanks to lot of lobbying by those companies) there was a few slaps on the wrist and some very weak changes none of which will do anything to encourage meaningful competition let alone growth. Mind you the PE companies themselves were pretty chuffed with the outcome of the review - so you know business friendly eh?
Meanwhile what this translates into for ordinary people is that more and more of them are giving up their pets because they can no longer afford to keep them.
Laughably the CMA's cloud computing review has now determined that AWS and Microsoft can adopt voluntary codes (apparently there was no conflict of interest in an ex Amazon executive being the Chair of the investigating authority).
A step change was always going to be challenging for Labour but the national leadership seem completely disinterested in providing one, in some cases this is because they are way to close to vested interests who in turn are not acting in the interest of functioning markets let alone ordinary people. I feel sorry for many decent Labour councillors who have gone down the road today, the national leadership has singularly failed them and the country so far.
