The Green Party has announced a £15 minimum wage for all workers, which is either a bold commitment to economic justice or a cry for help from a party that has spent the last six months watching Labour slowly backpedal on everything it promised in 2024. The Greens are accusing Labour of watering down worker protections, which is rich coming from a party whose last major policy announcement involved a complicated scheme to make compost mandatory in rental properties.
The £15 figure lands somewhere between ‘politically aggressive’ and ‘mathematically unhinged depending on which economist you ask’. Labour’s current position is that £15 is unaffordable without triggering mass redundancies, which is the standard argument made by anyone defending a wage floor that hasn’t moved in five years. The Greens’ counter-argument is that if we can afford to subsidise corporate agriculture and fossil fuel infrastructure, we can afford to pay people slightly more than they need to survive.
What’s actually happening here is straightforward: Labour promised workers’ rights during the campaign, got into government, looked at the spreadsheets, and decided that workers’ rights were more of a ‘nice-to-have’ than a core policy objective. The Greens, who have nothing to lose and no responsibility for actually governing anything, are now the party saying the things Labour said two years ago. This is not a coincidence. This is what happens when a centre-left party gets into power and discovers that keeping business happy is easier than keeping manifesto promises.
The minimum wage has been a zombie policy for years—frozen at nominal levels while inflation eats the purchasing power of anyone unlucky enough to earn it. A £15 minimum would represent roughly a 40 percent increase from the current rate, depending on age and employment status. Is it affordable? Depends who you ask. Small business owners will say no. Economists will say maybe. Workers will say yes, actually, they would quite like to eat regularly.
The Greens’ announcement is also a test of whether anyone still believes the Labour government when it talks about worker protections. The answer, based on polling and the fact that the Greens are now the ones making these announcements, is no. Labour has already signalled that wage floors are negotiable. The Greens have signalled that they’re not. One of these positions will sound more appealing to voters who spent the last decade getting poorer in real terms.
Neither party is actually going to implement a £15 minimum wage in the next parliament unless the political math changes dramatically. Labour won’t do it because it’s terrified of business lobby groups. The Greens won’t do it because they’ll never form a government alone. What will happen instead is that this becomes a baseline for negotiation—the Greens push for £15, Labour offers £12, they meet at £13, and workers get a modest real-terms pay rise that barely keeps pace with inflation. This is called political compromise. Workers call it getting screwed slightly less than before.
The actual policy debate—whether a higher minimum wage drives employment losses or whether it stimulates demand and creates jobs—is being drowned out by the fact that both parties are now competing to prove they care about workers. Labour is losing that competition because it’s actually in government and choosing not to do anything about it. The Greens are winning because they can say whatever they want without consequences. This is the natural state of opposition politics: promise everything, deliver nothing, wait for the other side to get tired.
What’s genuinely interesting is that the Greens felt confident enough to make this announcement without immediately getting hammered by business groups for being economically illiterate. A few years ago, any proposal for a £15 minimum would have triggered a coordinated media campaign featuring small business owners explaining why their margins couldn’t support it. The fact that this announcement landed with a shrug suggests that either the political consensus has shifted or business groups have given up pretending that paying people more is actually impossible. Probably both.
The headline will be that the Greens are pushing for a £15 minimum wage. The real story is that Labour’s worker-friendly messaging from the campaign has evaporated so completely that a fringe party is now the one saying the obvious things. This is what happens when a government chooses to disappoint its base immediately rather than gradually. The Greens didn’t suddenly become more pro-worker. Labour just became less convincing at pretending to be.
