Another great reason why proper induction and ongoing professional development for MPs matters! (And as somebody who has also had to refresh their understanding of what gilt yields mean in the last 24 hours, this isn’t a criticism of MPs, who also have far bigger demands on their time than I do)

Last week we published a research note by @geographyjim.bsky.social and colleagues on housing for disabled Londoners. Worth a read - it covers what we know about the ability of London's housing stock to meet disabled Londoners' needs: data.london.gov.uk/housing/rese...
A chart showing the proportion of households that contain an adult with different types of impairment, by tenure group. Social rented housing tends to have the highest proportion of adults with impairments, then owner-occupied housing, then private-rented housing. This effect is particularly pronounced for adults with mobility impairments.

There's no way "over half of Gen Z want a dictator" - our new study gets more like 6% This is vital to get right - we're sowing generational division, giving fake momentum to the sense that young people are rejecting democracy + missing the real message theconversation.com/only-6-of-ge...

A dot plot with clusters of constituencies that voted Labour, Conservative, Lib Dem and "Other" in the 2024 general election. The clusters are spread out by the percentage of households in each constituency that were private renters, showing that constituencies with high proportions of private renters were more likely to vote Labour.
