The shadow education secretary, Laura Trott, and the Liberal Democrats' education spokeswoman, Munira Wilson, have signed a letter to the chancellor urging action on student loan repayment rates. It is a rare display of cross-party agreement on an issue that has also drawn growing unrest among Labour MPs on the government's own side.

The letter, first reported by BBC News on 5 August 2026, also bears the signature of Tom Gordon, the Liberal Democrat MP for Harrogate and Knaresborough. Gordon is himself a Plan 2 borrower — meaning he took out his loan under the repayment system introduced for English students from 2012. He said he could see no end in sight to his own repayments and expected his debt to be written off after 30 years under the standard repayment terms.

Gordon argued that successive governments had changed repayment terms and increased interest rates after borrowers had already signed up. "No bank or mortgage lender could do this retrospectively," he said, drawing a direct parallel with consumer credit protections that, in his framing, graduates are denied.

Oliver Gardner, founder of the campaign group Rethink Repayment, said the letter showed the student loans crisis was "not a partisan issue." The grouping of signatories lends that claim weight: a Conservative shadow cabinet member, a Liberal Democrat frontbencher, and — earlier this year — more than 20 Labour MPs have all pressed the government to act.

That Labour pressure surfaced in February, when backbench MPs (ordinary members of Parliament who do not hold government or frontbench roles) described the system's interest rates as "rip-off" during a parliamentary debate and called for urgent reform. Lucy Powell MP went further in evidence to the Treasury Select Committee — a cross-party group of MPs that scrutinises government spending — calling the system "endless" and "unfair." The committee published its report scrutinising student loans on 7 July 2026, adding parliamentary weight to the case for overhaul.

The chancellor herself has conceded the problem. Since the Budget 2025, she has described the student loan system as "broken." In April, the government announced a cap on interest rates for millions of student loans at 6 per cent from September 2026, citing global inflation risks and conflict in the Middle East as justification for the intervention.

A government spokesperson, responding to the Treasury Select Committee's report, said ministers were "already taking decisive action" and would "continue to look for ways to make the student loan system fairer for students, graduates and taxpayers in a financially sustainable way." That formulation tracks a familiar Treasury tension: the need to acknowledge borrower grievance without committing to writedowns that would carry a cost to the Exchequer (the UK government's account, funded by taxation).

There are two things worth understanding about the policy backdrop. First, student loans in England are administered under reserved policy — meaning only the UK government in Westminster can change them. Education is devolved to Scotland, Wales and Northern Ireland, but the Plan 2 and Plan 5 repayment regimes that concern most signatories apply to English graduates and those who studied in England. Politicians from opposition parties at Westminster are pressing on a lever that only the UK government can pull for this group of borrowers.

Second, the political coalition now forming is unusually broad. When Conservative, Liberal Democrat and Labour figures converge on the same complaint — retrospective changes to repayment terms — the government's standard response that it is already acting may face sharper testing in the autumn. The Treasury Select Committee's report gives MPs a structured vehicle for that scrutiny, and the cross-party letter gives the issue a public profile that backbench debates alone rarely achieve.

The chancellor's "broken" admission, the 6 per cent cap, and the select committee report have each, individually, been treated by the government as evidence of engagement. What the signatories of this letter are pressing for is something more: a commitment not to change the terms of existing loans retrospectively. That is a harder line to hold. Every Treasury that has adjusted repayment thresholds or interest rate mechanisms has done so with an eye on fiscal cost, and the September cap itself is a symptom of that balancing act — a temporary measure against inflationary pressure rather than a structural reform.

For borrowers like Gordon, watching a balance that barely moves despite years of contributions, the distinction between a cap and a fix may feel academic. For the Treasury, the difference is measured in billions.
