Prime Minister Andy Burnham has been accused of a U-turn over political funding after newly reported correspondence showed that he previously backed a £500,000 cap on individual political donations and argued that the limit should be reduced further over time.
The disclosure intensifies pressure on the Government ahead of the Representation of the People Bill returning to the Commons, where Labour MPs are seeking to impose tighter restrictions on very large donations.
Burnham's Government is not currently backing a general domestic donations cap in the Bill, although Downing Street has indicated that the idea has not been ruled out permanently.
The accusation of a U-turn comes from campaigners and critics. The verified new development is that correspondence seen by The Guardian records Burnham supporting the principle of a £500,000 ceiling and subsequently arguing for that limit to fall.
Burnham previously backed £500,000 ceiling
According to correspondence reported by The Guardian, Burnham wrote to campaigner Shaun Bowler in May supporting a cap on political donations.
He argued that an initial £500,000 limit would help guard against the perception that a political party could be unduly influenced by a single wealthy individual or organisation.
A subsequent email reportedly went further, with Burnham saying he believed the ceiling should progressively be reduced rather than remain permanently at £500,000.
The correspondence is politically significant because ministers are now declining to support attempts to put a general domestic donations cap into the current elections legislation.
Campaigners accuse Prime Minister of U-turn
Campaigners have seized on the correspondence to accuse Burnham of reversing his earlier position.
Transparency campaigners argue that exceptionally large donations can damage confidence in the political system by creating the perception that wealthy individuals or organisations have greater access or influence than ordinary voters.
Burnham has not accepted that he has abandoned the principle permanently. The Government's position is that a general donations ceiling will not be introduced through the current Bill, while leaving open the possibility of future reform.
That distinction means it is safer to describe Burnham as being accused of a U-turn rather than stating as an uncontested fact that he has broken a formal promise.
Stella Creasy pushes tougher donations rules
Labour MP Stella Creasy is among those pushing ministers to go further on political finance reform.
Parliament records an amendment led by Creasy that would introduce an annual £100,000 cap on donations and gifts received by registered political parties, recognised third parties, regulated donees and permitted participants, subject to specified exemptions.
The amendment has not yet been considered by the House of Commons and no decision has been taken.
Fresh reporting says Creasy and campaigners have also argued for a transitional approach beginning with a higher ceiling before moving towards a substantially lower permanent cap.
Alex Sobel has tabled separate £1m cap
A separate amendment tabled by Labour MP Alex Sobel would introduce an annual £1 million donations cap.
That proposal contains provisions dealing with trade union affiliation fees and other forms of political funding.
Like Creasy's amendment, it remains undecided and has not yet been approved by MPs.
The existence of competing amendments illustrates that there is support inside Labour for a donations ceiling even though MPs differ over where that limit should ultimately be set.
Government still tightening foreign donations rules
The dispute concerns a broad cap on permissible domestic donations rather than all political finance reform.
The Government is separately pursuing tougher rules aimed at foreign financial influence, including a £100,000 cap on donations and regulated transactions from overseas electors.
Ministers are also moving to restrict political donations involving cryptoassets and strengthen rules governing corporate donors.
Burnham's Government therefore argues that the Bill already contains significant safeguards, even though it is resisting a general ceiling applying to wealthy domestic donors.
Trade unions concerned about impact of cap
Trade unions have raised concerns about how a broad donations limit could affect their ability to support Labour.
Union funding differs from large personal donations because much of it originates from political funds built from contributions by large numbers of members.
Supporters of a cap have sought to address that distinction through exemptions or special provisions for qualifying affiliation fees.
Critics of exemptions argue that any system must avoid creating loopholes that allow organisations to circumvent the spirit of a donations ceiling.
Pressure grows ahead of Commons debate
The row is likely to intensify when the Representation of the People Bill returns to the Commons.
Burnham is already facing pressure from Labour MPs over electoral reform, with a large group supporting a proposed National Commission on the voting system.
The political donations dispute adds a second internal argument over the scope of the Government's democratic reform programme.
For Burnham, the newly reported correspondence makes that debate more difficult because opponents can now point to his own earlier support for a £500,000 ceiling and a subsequent reduction in the limit.
