Kemi's been going hard against the renters bill. Of course, the Right have a point that regulation adds to the cost of the letting and that will probably at the margins reduce supply. And I'd expect the Right to make that point. Here's Kemi (or more likely one of her pals) though-
Worse than that, the landlord can only apply to get their own property back on the basis of a limited list of reasons.
What sort of market is it where you can’t decide what to do with your own property? This is a violation of the principle of freedom of contract.
Labour is also bringing in rent control through the back door, as judges will be able to determine a market rent instead of the law of supply and demand.
A market in which you have diferent rules to the ones you want. Any market with rules has limits on freedom of contract, by definition. Judges determining market rent isn't "rent control" either. Putting the phrase "market rent" in there is rather the giveaway.
What Labour is doing is boosting renter rights and trying to boost supply.. That seems to be a better approach than not boosting supply and having shitty rights.
