Afternoon.

It’s Wednesday 2nd September: Britain’s borrowing is getting expensive, we’ve just had our hottest summer on record, and apparently we’ve been wasting quite a lot of perfectly good space next to train stations.

Kettle on.

📅 On this day: In 1666, the Great Fire of London began in a bakery on Pudding Lane. It burned for four days and destroyed most of the medieval City of London, including old St Paul’s Cathedral.

The interest rate the UK Government pays to borrow money has hit its highest level in 18 years, right as Chancellor John Healey (the guy in charge of the Government's money) gets ready for his first Budget next month.

The Government raises cash by selling bonds (basically IOUs) that pay investors interest. Investors are now demanding more interest to lend to the UK, pushing the rate on 10-year borrowing to 5.268%, the highest since 2008.

It's not just us. Borrowing costs are rising globally, but renewed fighting between the US and Iran isn't helping. Oil prices have jumped because traders are worried supplies could be disrupted through the Strait of Hormuz, the narrow waterway that carries around a fifth of the world's oil.

Why does that matter for us? Pricier oil can push inflation up, which can keep interest rates higher for longer, which makes it more expensive for the Government to borrow. More of our tax money then goes on interest payments instead of, well, anything else.

Analysts at Pantheon Macroeconomics reckon this could shrink the Chancellor's financial wiggle room from £23.6bn to around £13bn. That's roughly the buffer he has against his own borrowing rules, so a smaller one leaves less room for tax cuts or extra spending at the Autumn Budget.

If you spent most of August wondering whether Britain had quietly been relocated several hundred miles south, there is now some data to back you up.

The Met Office has confirmed that summer 2026 was provisionally the hottest UK summer since records began in 1884, which is also roughly the last time our office fan was cleaned.

The UK’s average temperature was 16.5°C, beating the previous record of 16.1°C set all the way back in... 2025.

England, Wales and Northern Ireland all set new summer records, while Scotland had its joint-sixth warmest. The temperature reached 38.1°C at Kew Gardens in August, and 54 Met Office weather stations broke their own all-time daily maximum records during the summer.

The Met Office estimates human-caused climate change made a summer this hot around 130 times more likely. And there’s a fairly conspicuous pattern forming: the five warmest UK summers on record have now all happened since 2003.

So yes, it was hot. Statistically, scientifically, record-breakingly hot.

Britain needs more homes. It also turns out we have quite a lot of surprisingly underused land next to places specifically designed to get people from A to B.

New analysis from Centre for Cities estimates Britain's 12 largest cities could have space for around 1.2 million more homes near inner-city stations if those areas were built as densely as comparable cities in France and Japan.

The biggest gap is London, with more than half a million potential homes, followed by Glasgow with 183,000 and Manchester with 134,000. In Sheffield and Liverpool, housing is actually less dense around some stations than it is farther away.

The Government is already changing planning rules to make it easier to build homes around stations. But Centre for Cities argues planning permission is only half the battle. It also wants mayors to get greater control over station land and a quicker system for releasing land owned by Network Rail.

For once, the answer to Britain’s housing shortage might be sitting right under our noses. Or at least next to Platform 2.

England and Wales's Chief Inspector of Probation has warned too few staff are handling too many cases, right as the Government tries to ease overcrowded prisons.

Here's the problem: when offenders are released from prison, probation officers take over, supervising them in the community, checking they stick to their release conditions, and trying to stop them reoffending.

Releasing more prisoners early means more people for those officers to supervise. But the Chief Inspector says workloads are already too high and the service is under serious strain. So easing pressure on prisons risks just shifting it onto probation, a bit like solving a traffic jam by moving it to a smaller road.

There are a couple of changes parents in England might appreciate as the kids head back. First, all pupils whose families receive Universal Credit can now qualify for free school meals, without the previous separate earnings limit. The change is expected to make more than 500,000 additional children eligible.

There are new uniform rules too. Schools can now require no more than three compulsory branded items, or four for secondary and middle schools if one of them is a tie. The idea is to let parents buy more of the basics from supermarkets rather than being tied to one supplier.

So, school itself remains compulsory. Spending a small fortune on jumpers with tiny logos, rather less so.

Scotland already has a £2 single bus fare pilot across the Highlands and Islands, and the Scottish Government now plans to expand it further. The next target is the Strathclyde region, covering Glasgow and much of western Scotland, with the Government ultimately promising a nationwide £2 cap by the end of this Parliament.

There’s no application needed in the existing pilot: passengers simply board a participating service and pay no more than £2 for a single journey. No forms, no codes, no 47-page eligibility guide. You get on the bus and pay £2.

Matt Clifford, one of the main architects of the UK Government’s AI strategy, has taken a senior job at Anthropic, the American AI company behind the Claude chatbot.

Clifford has advised both Conservative and Labour governments on AI and played a major role in drawing up the Government's AI Opportunities Action Plan.

At Anthropic, he’ll lead the company’s dealings with governments outside the US. The move has inevitably prompted questions about the familiar Westminster “revolving door”, where people move between influential government roles and companies affected by government policy.

Clifford will also remain chair of ARIA, the publicly funded UK agency that backs ambitious science and technology research. Anthropic says arrangements will be put in place to manage potential conflicts. Presumably by asking Claude to “manage potential conflicts”.

The summer transfer window has closed, meaning Premier League clubs must finally stop spending money on footballers for a few months.

And spend they did. Premier League clubs splashed around £3.46bn this summer, breaking the record for a second year running.

Manchester City made the biggest deadline-day splash, signing Enzo Fernández from Chelsea for £125m, equalling the British transfer record. Liverpool paid an initial £107m for PSG winger Bradley Barcola, while Tottenham signed Newcastle midfielder Sandro Tonali for a fee that could reach £100m.

Four of the eleven priciest signings in Premier League history happened in one summer. Financial Fair Play remains, somehow, a real phrase people use.

Finally, scientists have discovered that when the going gets murky, fish get sociable. Researchers at the University of Bristol studied how three-spined sticklebacks (a type of fish) behave when their water becomes cloudy with things like mud, silt and algae.

In murkier water, the fish became more coordinated as a group, apparently helping them compensate for not being able to see as well. Finding food still took longer in cloudy water, but fish in larger groups responded faster than those in smaller ones.

The study, published in the Proceedings of the Royal Society B, suggests changing their social behaviour could help sticklebacks adapt when visibility gets worse.

So when visibility drops, stick close to someone who looks like they know what they're doing. Sensible advice for fish and tourists navigating the London Underground.

Have a great day.

See you tomorrow.
