The Labour Party under Keir Starmer saw a dramatic shift in voter support, leading to a crisis that now faces Andy Burnham. Labour's lost voters include traditional leftwing supporters and union allies, posing a challenge for the new leader. This article visualises the decline and explores paths to recovery.
The Union Fracture Under Starmer
Unions have been foundational to Labour since its inception, but donations have steadily declined over the past 20 years. Under Starmer, this trend accelerated, hitting a historic low in 2025. The rupture began with Neil Kinnock, widened under Tony Blair, and worsened with Starmer's tenure.
Key Events in Union Relations
In 2022, Starmer sacked Sam Tarry for appearing on a picket line, angering union leaders. By 2023, Unite's Sharon Graham warned against treating union support as a blank cheque. The Birmingham bin strikes further strained ties, leading Unite to suspend deputy leader Angela Rayner's membership.
| Leader | Union Donations (Annual Average) | Net Approval Rating |
|---|---|---|
| Tony Blair | £5.2M | +15 |
| Ed Miliband | £4.1M | -10 |
| Keir Starmer | £2.3M | -66 |
Electoral Decline Visualised
Starmer's net approval rating dropped from -3 at office entry to -66 by September 2025, the lowest since 1977. Labour's lost voters include leftwing supporters who defected to smaller parties or abstained. The party's 2024 landslide masked underlying discontent.
Key Takeaways for Burnham
- Rebuild trust with affiliated unions through dialogue and policy alignment.
- Address leftwing voter concerns on public ownership and welfare.
- Improve communication on economic policies to regain centrist support.
- Learn from Starmer's missteps in handling internal dissent.
Path Forward: Avoiding Bear Traps
Burnham must navigate a fractured base. Labour's lost voters expect concrete actions, not just rhetoric. Prioritising union relations and leftwing policies could stem the decline. Data shows that restoring approval ratings requires a multi-pronged approach.
