Britain currently has no cap on political donations. Is this freedom, or madness? We hear both sides in this week’s Debate
YES: In the first quarter of 2026, just two donors accounted for a third of political donations
There’s no such thing as a free lunch. So, it should send alarm bells ringing that very large political donations are on the rise in Britain. In 2015, donations of £1m or more made up just one per cent of all political giving. By 2024, they made up over a third.
The trend has only accelerated. In the first quarter of this year, just two donors accounted for around a third of all reported political donations. When political parties depend on a handful of mega-donors, those individuals have increased access to senior politicians – including ministers – and even influence over policy. This has given rise to justified concerns that policy is being skewed in favour of private interests.
A £100,000 annual cap on political donations would prevent this. £100,000 is a substantial enough cap to enable parties to fundraise privately without the need for additional public funding, while being a low enough figure to prevent any one individual buying outsized influence over those who govern us.
Parties raised millions last year in donations under £100,000. A donation cap at this level encourages parties to function as they are expected to in a healthy democracy: building broad support, rather than leaning on a few wealthy backers.

The government’s recent reforms cap donations from overseas. But the problem was never a donor’s postcode, it is the size of the cheque, whether written in Mayfair or Monaco.
Polling shows the public overwhelmingly support the government taking action on donations. Parliament should back a £100,000 cap and take big money out of British politics.

A £100,000 cap on political donations sounds like a neat answer to Westminster sleaze, but its proponents risk creating a much bigger problem: taxpayer-funded political parties.
Once private funding is choked off, parties will not magically make politics cheaper or humbler. Instead, politicians will demand more and more taxpayers’ cash to keep their machines running. Taxpayers already fund Short Money, policy development grants and election mailings – they should not be forced to bankroll the whole circus.
It’s also fundamentally unfair. Why should a Labour voter have to subsidise Conservative social media ads? Or a Conservative voter fund Labour leaflets? And why should millions of people who dislike every party be compelled to pay for any of them?
I fear it would also make politics even more remote. Parties that rely on supporters must persuade people to give them money, time and trust. Parties that rely on the Treasury can afford to ignore them. Westminster would become more professionalised, more insulated and even less connected to ordinary voters. Nor would a cap eliminate influence, as it would simply shift power towards those with institutional advantages, friendly campaign groups, unions and clever lawyers who can navigate the rules.
The better answer is radical transparency, where private donations are disclosed quickly, clearly and in full, and where MPs are quickly reprimanded for not doing so. And any suspicious funding should be investigated properly, with voters and journalists alike being able to see who is funding whom.
Cleaning up politics should not mean that taxpayers are forced to foot the bill.

THE VERDICT
Recent furore over generous ‘gifts’ to Nigel Farage along with a wider rise of so-called ‘mega-donors’ has prompted urgent questions over whether the UK’s rules around political donations are in need of reform. Currently, there is no cap on how much donors can give to their selected party, though in March the government announced a new £100,000 limit on donations from British citizens living abroad (a measure which will especially hit Reform, funded primarily by two overseas donors) and some are now calling for the cap to be extended to all donors.
As it stands, Britain’s lack of cap makes it uniquely liberal compared to other countries: in France, donors can only give €7,500 a year, in Canada less than $2,000. In that context, £100,000 certainly feels fairly reasonable. While Mr Yarwood is right to be concerned about an alternative of state-funded political parties, it seems fair to agree with Mr Hames that a £100,000 limit would remain generous enough not to necessitate such, while also going some way to fighting corruption.
