Quite - and I don’t say this lightly - an extraordinary poll for the Welsh Parliament election in May via @itvcymruwales.bsky.social 👇👇
The Polanski surge is hitting the Greens in Wales and Reform appear to have plateaued. A big Plaid lead and Lab/Cons in 4th/5th.

Yes: we spent unfathomable millions on a bridge to nowhere because process forced us to. But we also spent £100m on an unusable prison because of recklessness about process. State capacity is not a problem that bold leadership will magically resolve.

A very personal year note from me. 2025 has been a difficult year - navigating burn out and loss. Forcing a pause, a lot of reflection, and a much-needed re-evalation of how I work and who I am.

The media is constantly trying to push the angle that young people, particularly young men, are about to go, if not already going, fascist and young folk refute that every time at every juncture. I've got more time for them than any other demographic by a full country mile.
Young people love Plaid and hate Reform
There has been a lot of talk about Reform being really effective at reaching young people.
However this polling suggests that just 5% of those aged 18 - 24 would vote for them.

How Google Maps quietly allocates survival across London’s restaurants - and how I built a dashboard to see through it
I wanted a dinner recommendation and got a research agenda instead. Using 13000+ restaurants, I rebuild its ratings with machine learning and map how algorithmic visibility actually distributes power.

This is pretty massive.
There is scant detail so far but they say "solar radiation" has caused problems for some aircraft.
This *could* be related to single-event upsets, where cosmic rays trigger computer errors. I've asked Airbus if they can share more detail.

Last Friday night and Saturday morning, Monmouthshire was hit by devastating floods. Monmouth’s high street, a place that I’ve barely known wet before, became a high roaring river (see the pictures of how it lies normally, as it did on Thursday, with the flooded Waitrose high above).
