This is what #Farage isn't telling people.
The ONS population pyramid projections are terrifying for the public finances.
Green is the 2018 population.
The Gray shows far more older people are going to need public services, with fewer younger people to pay taxes.
#Migration is just a scapegoat.

Last time I checked, it was the Conservatives who
- changed the rules so half the board could be political appointees
- made ex-No. 10 man Robbie Gibb chair, who exerted pressure over appointments.
Maybe that's the kind of political interference Harding meant.

This graph is great because it goes beyond a thousand opinion pieces about age of driver.
You can see at a glance the risk adjusted for the amount of driving.
What can we do to reduce deaths of the very old and young on the road?

Council Tax is 1 of 2 taxes on wealth the UK has.
Yet the rich pay a lower percentage rate than the average person.
If we want to rebalance the economy, reforming Council Tax is one of the first places we need to look.

We’re told markets are always efficient. That prices reflect value. But if that’s true, why does everything feel like it’s falling apart?
My new video breaks down the lie at the heart of modern economics—and how it’s gone too far.

Every metric of GP satsifaction is lower. Every metric.
That's an astonishing indictment of @snp.org policy.
It tells of a workforce stressed to breaking point.

While Scotland has recruited more GPs (that's a good thing), fewer hours are actually being done.
That's a sign the job is becoming stressful and GPs aren't being rewarded proportionally to the hours they put in.
Is activity-based pay or going back to QOF something that would help?

Generational inequality in one chart.
You’re under 40. You’ve bought a home, have a car, and save a few grand a month.
You’ve done everything right — and you’re still near the bottom of the UK’s wealth distribution.
This isn’t failure. It’s a system where wealth accumulates above you.

Let's inject some facts into the discussion about Ukraine.
This is a visualisation of 2024 defence spending.
Europe can outspend Russia, but only if we work together and the US doesn't work against its allies.

The co-variance point oversimplifies. Yeah it's a funny retort, but the point it's making is wrong. It's silly to think the only thing about life expectancy that matters is GDP.
This graph shows life expectancy over time for different countries. There's obviously significant variation!

But who will hold the system to account for not having the beds for crisis teams?
More Calocanes WILL happen without major Mental Health Service investment

Wes Streeting did a great speech defending the core principles of the NHS.
Lewis Goodall's questions focusing on Westminster bubble based talking points, trying to stoke a controversy.
We need informed discussion, not gossip and tittle-tattle, to fix the state.

Every bit of orange in these graphs is a doctor that gave up their licence and never came back.
If we could get them to stay instead, that would be an extra boost to getting waiting lists down.
What is needed to encourage doctors to stay?

These graphs prove Scotland has an NHS productivity problem; and it isn't the fault of us hardworking NHS staff.
Graph 1 shows we have about 10% less emergency activity, and about 20% less elective activity.
But Graph 2 shows we've got more staff than ever!
What we need is more efficient systems.

Scotland no longer spends vastly more on health than England.
Not the headline the #SNP wants.
The truth is we need to look at increasing productivity, not just increasing spending.
The SNP isn't really talking about productivity, and isn't really doing more spending.

In case anyone were to assume my concern over declining fertility rates is confined to female reproduction.
Smoking, weed, diet and plastic derivatives are all implicated in reducing male fertility, but not yet proven.
Where are the policy responses?

It's very hard not to conclude that the falling birth rate is largely due to the widespread availability of contraception.
While being sold a chance to delay "until you're ready", many women are ending up not having them at all.
My main concern is - are women's choices being fully informed?

5/ The human cost of this crisis is clear. Over 50% of junior doctors report depression, stress, or burnout. Consultants and SAS doctors fare slightly better, but the trend is unmistakable: the NHS workforce is breaking under the strain.

4/ On paper, NHS doctor numbers are rising. But look closer: much of this growth is in junior roles, while registrar positions are stagnant. Training caps limit progression, leaving highly trained doctors underutilised while the NHS struggles with senior staff shortages.

3/ Secondary care vacancy rates remain persistently high, especially in nursing (10% or 30,000) and medical roles (~6% or 10,000). This isn’t just a recruitment problem—it’s also about retention. Burnout, low morale, and limited progression opportunities drive people out of the NHS.

2/ England has one of the lowest numbers of doctors per capita among OECD nations—just 3.2 per 1,000 people. Compare this to Austria (5.5) or Germany (4.5). Understaffing isn’t just a resource issue; it’s a policy choice that stretches staff and harms patients.
