Largest rich vs. poor gap in inflation since the 00's. For much of the last ten years, inflation has been very close for richest and poorest. Higher fuel and food prices hit poorest hardest - so their inflation has taken off faster in 2022 (blue line, far right of chart).

It's technically true but not informative to say, as Chancellor Jeremy Hunt did, that the UK saw the biggest growth in the G7 last year. The UK's economy didn't really grow much in 2022. It looks good compared to 2021 because that year included lockdowns.

How to balance risks and benefits of vaccination for you. 1-in-a-million is roughly your chance of getting murdered in the next month, or dying in a 250-mile car trip. That's pretty small full stop. And, for most, it's small compared with Covid risks.

Rumours of higher case rates in vaccinated over 40s (vs unvaccinated) have been greatly exaggerated. We don’t know how many unvaxxed over 40s there are. So we estimate. Rates = cases (known) / people (estimated). Get the people number wrong and you’ll get the rates wrong.
