There is a long and noble tradition in British politics of politicians doing things that are petty, vindictive, and constitutionally dubious — but at least having the good grace to pretend otherwise. Zia Yusuf, Reform UK's home affairs spokesman, has dispensed entirely with the pretence.

This weekend, Yusuf announced that a Reform government would build immigration detention centres capable of holding up to 24,000 people — and that these facilities would be deliberately located in areas that vote Green. Not near ports. Not in places with available land. In places that voted for the wrong party.

“We will prioritise Green constituencies and Green-controlled councils.”

He said it with the energy of a man announcing a particularly satisfying chess move rather than, say, a major infrastructure policy.

The reasoning? The Greens support open borders, therefore Green voters should host the consequences of open borders. It is, Yusuf explained with a straight face, "an important exercise in democratic consent."

One assumes the irony of a party that wants to abolish planning rights for local communities describing this as democratic consent was not lost on him. It was almost certainly lost on nobody else.

The Policy, Explained Simply

Here is how Reform's detention centre siting policy works:

• You voted Reform? No detention centre for you. You've earned it.

• You voted anything else? Possibly a detention centre, but we'll sort something out.

• You voted Green? Congratulations. We're building next to the community allotments.

It is, stripped of its pseudo-philosophical justification, a policy that says: if you didn't vote for us, we will use the levers of the state against you. Fraser Nelson of The Times — not exactly a left-wing firebrand — called it "a new departure for UK politics: rejecting the idea of PM-for-all." Simon Clarke, director of the right-wing think tank UK Onward, described it as "abhorrent," adding that it "would almost certainly be deemed an abuse of ministerial power for political purposes, and as such would likely be struck down in court before ever being implemented."

Which is, admittedly, quite the endorsement from your own ideological neighbourhood.

The Greens' Response

The Green Party reacted with predictable — and not entirely unwarranted — outrage. A party source told Middle East Eye the pledge was "reminiscent" of racist Conservative campaigning in the 1960s. Deputy leader Mothin Ali called it "abhorrent." A spokesman accused Reform of making "unserious announcements" to distract from its plan to privatise the NHS.

The Greens' official policy, it should be said, does include an aspiration toward a world without borders. Yusuf has latched onto this with the glee of a man who has found a quote he likes and is absolutely going to run with it, regardless of context, nuance, or the fact that "aspiring toward a world without borders" and "therefore you deserve a 24,000-capacity detention facility on your doorstep" is, at minimum, a substantial logical leap.

One does wonder whether Reform has fully thought through the aesthetics of this. The Green Party's core voters — cyclists, farmers' market enthusiasts, people who compost — are not, generally speaking, the demographic that responds well to being told a detention centre is coming to their village. If anything, it may prove the world's most effective Green Party voter registration drive.

The Timing

It is worth noting that Yusuf made this announcement three days before local elections in which both Reform and the Greens are expected to make significant gains.

This is either brilliant political provocation — force the Greens onto the defensive, make the election a binary choice between Reform and the Greens, win the culture war — or it is the sort of announcement that sounds good on a Sunday and will be cited in textbooks on political overreach by Tuesday.

Possibly both.

Reform is targeting former industrial towns. The Greens are targeting cities — London, Cambridge, Newcastle, Manchester. The battleground is drawn. And now, hovering over every Green-held ward like a planning application from hell, is the spectre of a detention centre.

What This Is Really About

Let's be honest: this is not a serious infrastructure policy. It is a political stunt, a provocation, a giant flare fired into the sky three days before a vote. The announcement carries all the practical heft of threatening to put a motorway through someone's back garden on the grounds that they once said cars were bad for the environment.

But it is effective as a political manoeuvre, and that is the point. Reform wants to fight the next general election as a binary choice: them versus the Greens, hard borders versus open ones, the people who worry about immigration versus the people who say it's fine. Every news cycle that treats this as a genuine left-versus-right axis is a news cycle Reform has won.

The Greens, to their credit, seem to understand this. Their response has been to pivot rapidly back to the NHS and housing costs — sensible territory, where Reform has less to say and the Greens have more.

Whether voters are paying attention to the pivot, or to the detention centre announcement, probably depends on which newspaper they read. And in Britain in 2025, that is a gap wide enough to park approximately 24,000 people in.

If you enjoyed this, share it with someone who lives in a Green ward and has strong opinions about planning applications.
