South Leicestershire.

South Leicestershire is a network of small towns and villages on the southern fringe of the East Midlands, with no single settlement dominating its 102,738 residents. The largest built-up areas -- Blaby and Whetstone, then Enderby and Narborough, Lutterworth, and Broughton Astley -- each hold a tenth of the seat or less, ringed by a substantial rural and dispersed population. The population is older than the national figure, with a median age of 44, overwhelmingly White at 94.1%, and rather less degree-educated than average at around a third. Local services are split between two district authorities: Blaby District Council, which accounts for eleven of the seat's wards, and Harborough District Council, which covers nine.

The parliamentary picture has narrowed sharply. The Conservatives held the seat in 2024 on 35.6%, with Labour second on 24.8%, a far thinner result than the 64% the party took here in 2019. Beneath that, the ward map remains predominantly Conservative -- the party leads in twenty-three of the most recent contests -- but the Liberal Democrats hold eight wards and have run the Conservatives close in several Blaby contests dating from 2023. More recently, Reform UK has taken two wards on fresh polling, suggesting the field below Westminster is broadening. Alberto Costa, the Conservative who has held the seat since 2015, sits within this shifting picture rather than above it.

The direction of travel here is one of erosion rather than upheaval: a long-held Conservative seat where the 2019 margin has thinned and challengers have multiplied. Recent local coverage has had a procedural, consultation-heavy character, dominated by the prospect of council reorganisation and by large-scale housing pressure on the district's farmland -- administrative rather than adversarial in tone. On the figures available, the seat reads as Conservative-leaning but no longer comfortable, its lower tiers contested from two directions at once. Whether that erosion settles or deepens is, for now, an open question.
