Cap donations is a free-to-use policy tool to explore the potential impact of annual limits on political contributions.
It allows you adjust key policy choices and explore how these might affect:
- Conservative Party
- Cooperative Party
- Green Party for England and Wales
- Labour Party
- Liberal Democrats
- Reform UK
- Scottish National Party
Methodology
The tool uses data reported by political parties and published by the Electoral Commission. We standardised this data, allowing us to calculate how much any donor has given over time. Our modelling assumes that when a donor has given in amounts over the cap, they would have spread as much of this excess as possible over the next five years. We have also taken into account when donors have made contributions to politicians and other political campaigners covered by the rules.
