Zack Polanski in April 2016 citing San Francisco as a prime example of why rent controls don’t work and stifle housing supply 🕊️ pic.twitter.com/4eBmtJi6EU— Purav Menon (@profavi_) June 1, 2026

When he is not wanging on about Gaza, prolific political shapeshifter Zack Polanski loves nothing more than banging the drum for rent controls. The Green leader has claimed that price caps would have saved tenants £3,000 a year had they been introduced in 2022, and put £18 billion of purchasing power back into people’s pockets.

Well, quelle surprise: it seems Polanski did not always embrace such fantasy economics. Indeed, he actively argued against them. Video footage from April 2016 captures the wannabe Che Guevara trying to school his future colleague, Brighton Pavilion Green MP Sian Berry, on why rent controls stifle supply.

At a panel event on housing in London, Polanski is caught saying: ‘I love Sian’s passion about rent caps and rent control, and I would be passionate about them too if they were proven to work.
