How this prediction was made
- Fallback (no historic match) . No prior contest results in DC bundle for this ward (likely 2026 boundary change). Synthesised prediction from council-level GE2024 aggregate + national 2024→2026 swing + county-2025 anchor where available, restricted to the parties on the 2026 ballot. Marked low confidence.
- National-share calibration . Aggregate-predicted vs national-polled mismatch corrected at strength 0.65. Multipliers — Labour ×0.82, Conservative ×1.00, Reform UK ×1.15, Liberal Democrats ×0.96, Green Party ×1.12, SNP ×1.00, Plaid Cymru ×1.00.
