South Northamptonshire.

South Northamptonshire is a rural seat in the East Midlands, its population of roughly 108,000 spread across two small market towns and a wide scatter of villages rather than gathered into any single centre. Brackley, the larger town, holds about a sixth of residents, with Towcester a little under a tenth; beyond them, a quarter of the seat lives in dispersed rural settlement, and the rest in villages such as Roade, Deanshanger, Middleton Cheney and Bugbrooke. It is an older and notably homogeneous area, with a median age in the mid-forties, a degree-educated share around a third, and a population that is almost entirely White by the last census. The character is dispersed and small-town, not urban.

The local political picture is harder to read from the record than the parliamentary one. No recent ward-election results are held for the seat, so the direction of travel at council level cannot be traced with any confidence here. The general-election figures are clearer. The Conservatives held the seat in 2024 on 35.7 per cent, with Labour second on 28.9 per cent, a margin of under seven points. That marks a sharp narrowing from 2019, when the Conservative share stood above 62 per cent. Sarah Bool, returned for the Conservatives in 2024, has shown no whipped dissent over the past 90 days, and lists the economy, health and defence among her main subjects in the Commons.

What has changed, then, is less the result than the gap. A near-thirty-point cushion has become a single-figure lead, which on the figures available leaves the seat more contested than its long Conservative history would suggest. Recent local coverage has had a markedly administrative and planning-led tenor, with development and infrastructure the recurring themes and a measure of local opposition pressure attached to them. None of that yet points in a settled direction. The seat appears to sit, for now, somewhere between safe and genuinely competitive, its standing dependent on whether the 2024 compression proves a floor or a trend.
