Good morning. Here’s what matters today.

The Holborn and St Pancras byelection next week is tightening in a way that should interest anyone watching UK political risk. The Greens’ Zack Polanski describes it as “probably 50/50 right now” — Starmer’s old seat, and a Labour loss there would be an early embarrassment for the Burnham government. Separately, a Guardian investigation has surfaced a lobbying conflict worth watching: Martha Dalton, whose firm worked for Palantir as recently as 2025, played a senior strategic role in getting Burnham into Downing Street. Given the government’s expected posture on defence tech procurement, that relationship will attract scrutiny.

On energy, the EU is reportedly considering releasing 50 million barrels of diesel reserves under pressure from Trump, who has threatened to ban US fuel exports to Europe if the bloc doesn’t act. The FT notes the move is already pushing diesel prices sharply lower. This is a live situation — watch the spread between European and US diesel benchmarks, and whether any formal reserve release gets announced before the weekend.

Zelenskyy told the FT that Putin has explicitly ordered Russian military commanders to abandon the rules of war — that “there are no rules now.” That’s a direct quote attributed to Zelenskyy in the FT. The practical battlefield implications are already visible in strike patterns, but the significance here is that Kyiv is now framing this publicly as a doctrinal shift, which changes the diplomatic calculus for European capitals weighing further military support.

Friedrich Merz is in real trouble. His approval rating has hit a record low following CDU losses in three consecutive state elections — defeats to both the far right and the left. Germany’s political centre is fragmenting faster than markets had priced, and with the federal budget still unresolved, this is not a stable backdrop for European fiscal coordination.

On AI costs, the FT has a piece worth reading ahead of the frontier lab IPO cycle: powerful AI tools are burning through enterprise budgets faster than expected, and the pricing models are under pressure. The framing matters — if cost control becomes the dominant enterprise AI story heading into 2027, it changes the revenue assumptions underpinning valuations for OpenAI, Anthropic and others. The Economist is separately flagging that AI may materially shrink the tax base, though that piece is podcast-length rather than a full analysis.

The US federal cybersecurity picture is deteriorating. Two agencies were breached within a single month, with Ars Technica reporting a significant volume of sensitive data compromised. No attribution confirmed in what’s available, but the pattern is notable for anyone with exposure to US government contracting or defence supply chains.

The Holborn and St Pancras byelection takes place next Thursday 8th October. Polanski’s own “50/50” framing makes it one to watch closely.
