The Electoral Commission, the UK's elections and party-finance regulator, has opened a review of the campaign spending framework as a whole, with recommendations due in July 20271. It covers party and candidate spending limits, how party and candidate spending interact, and the reporting rules; ministers asked for it in July. Chief executive Vijay Rangarajan said how much parties and campaigners can spend "is a significant part" of whether people believe the rules are fair. The review deals with spending only: limits on what a single donor may give are a separate question, now before peers as amendments to the Government's elections bill, which the Commons sent up with a cap only on overseas electors' gifts.

Electoral Commission to review spend caps
The elections regulator has opened a review of party and candidate spending limits, at ministers' request, with recommendations due in July 2027.
The Electoral Commission will report on party spending limits in July 2027.
Deep Analysis
The Electoral Commission is the independent body that regulates elections and party money in the UK. It sets no laws itself but advises Parliament and enforces the rules. There are limits on how much a party can spend nationally and how much each candidate can spend locally during a campaign. Ministers asked the Commission to review those limits. Its recommendations are due in July 2027. Ministers and Parliament then decide whether to change anything.
Spending limits are set as fixed sums and changed by ministerial order, so their level depends on the government of the day. The 2023 rise was made that way, without a recommendation from the Commission.
The Commission has long found the boundary between national party spending and local candidate spending hard to police. The Commission fined the Conservative Party in 2017 over how it reported 2015 battlebus costs, a case that turned on exactly that line.
Digital advertising lets national money reach voters in chosen seats, which strains a system designed around leaflets and posters.
- Consequence
Any change to limits would need a ministerial order or new legislation after July 2027, leaving under two years before the latest general election date.
- Opportunity
The review gives the Commission a formal channel to recommend lower limits as a partial answer to very large donations, which spending caps can blunt even without a donation cap.
