Just watched two founders on a panel, both who sell services to the NHS, both just answered a question about how to sell into the NHS by saying that it's too hard, and they shouldn't try. "Choose another vertical", one said. This makes me sad. If worked in the NHS it would be make me very sad.

I'm not generally pro people wrecking shit to make political points, but I'm glad this lot got found not guilty. They seem like a good bunch. And they make a pretty compelling case that JP Morgan aren't, and that breaking a few windows was, in this context, fine. So good for them 👍

This feels like a case were the law doesn't really fit the situation to me: or at least one where professional obligations, legal obligations, realpolitik and personal principles all collided in a way that precludes there being an obvious ethical answer.

I went to see a play based on transcripts from the first trial, it was extremely good and (although clearly curated) the transcripts made a pretty powerful case for the idea that these medics did in fact have a "lawful excuse" for their actions www.southbankcentre.co.uk/whats-on/in-...

ETA: I forgot to mention one of the worst things - that it's retrospective, and will apply to people already here, already working towards settlement but not there yet. People who've moved here, put down roots - only to have this government yank them out. An extraordinary breach of faith. Awful.

Here's a word I don't use often: shameful. But this policy is shameful. I'm ashamed that my government has proposed it. It's arrogant, it's cruel, it won't work in any meaningful way, but it will make our country a worse place. Please respond (before midnight). It's so, so bad gov.uk/government/c...

Instead we have one that starts from suspicion. Settlement should be a sensible process of integration that recognises a migrant's future as being here: but under this policy it's a hostile, exclusionary, decade-long++ trial. It presumes that a bureaucracy can judge who deserves to belong. It can't.

Like @bmwelby.bsky.social said: this should mostly be a policy about how to help people to feel at home and build a good life here, with a bit of sensible protection to help us to avoid letting in too many murderers. bm.wel.by/2026/01/14/w...

What ‘earned settlement’ tells us about belonging, character, and the country we are becoming - bmwelby's blog
Over the weekend I spent some time responding to the Home Office consultation (it closes in mid-February) on proposed changes to settlement and what it calls “earned residence”. Please engage with it....

And then there are the children. A child brought here at 3 whose parents face a 15-year wait could grow up entirely in this country and still face years of uncertainty about whether they can stay. Children don't choose to migrate. Treating such a child's belonging as provisional is terribly cruel.

Harry Metcalfe @harrym.com · 12/02/2026
Across the whole thing, they mistake measurability for meaning. A person who's raised kids here, made friends, participated in local life is integrated whether or not they can pass a (fatuous) multiple choice exam. Real integration is lived and worked, but lived things don't fit on forms. Don't try!

Harry Metcalfe @harrym.com · 12/02/2026
The word is revealing and it matters. If you tell people this is about "character" you're saying those who fail it are deficient as human beings. Not that they didn't meet a practical requirement: that they weren't a good enough person. Who do they think they are, to presume to say such a thing?
161
Harry Metcalfe @harrym.com · 12/02/2026
The first pillar is "Character". But what the policy actually measures is criminal records, English, and earnings. Those are things you can observe: character is not. Character is morals, resilience, humaniness, the capacity for growth. The state cannot assess it and shouldn't pretend to try.

Harry Metcalfe @harrym.com · 12/02/2026
We begin with the Home Secretary's foreword, which is something else. She opens with her own family's migration story, declares herself a patriot, then lays out a system designed to keep people like her parents in constant limbo for a decade or more. The lack of self-awareness is kinda mindblowing.
