Green Party Returns Leader's Donation Over Electoral Law Breach
The Green Party of England and Wales has sent back a donation from its own leader, Zack Polanski, after discovering it broke UK electoral law, BBC News reported on 26 June 2026.
Political parties in the UK can only accept donations from certain sources. For individuals, this means they must be registered on the electoral roll. Polanski does not meet that requirement, so the party returned his money and reported the matter to the Electoral Commission, as the law demands.
The Independent says this is the first time a major British party has had to reject a donation from its own leader. The Telegraph describes it as something without recent precedent among the mainstream parties.
These rules are not new or secretive. They have been central to UK campaign finance law since the Neill Committee reforms of the late 1990s. Any party treasurer or compliance officer will know them well. A party leader falling outside them is an unusual administrative problem — and one the party's internal checks should have caught before accepting the donation, not after.
The straightforward part is what happens next. Inadmissible donations must be returned within 30 days, and the party must tell the Electoral Commission. The Greens appear to have followed this procedure correctly. The more awkward question is why the donation was accepted in the first place.
For Polanski, elected Green co-leader in 2024 and confirmed as sole leader since, the timing is uncomfortable. The Greens have made institutional reform and principled politics a core part of their message. A compliance slip involving the leader's own finances — however routine the fix — gives their opponents ammunition and leaves unanswered questions about why no one checked his electoral-register status before the donation landed.
The broader context here matters. This kind of administrative failure is exactly what opponents use to suggest that a party's stated values do not match its practice. The Greens will need to give straightforward answers about what went wrong with their internal processes.
