Transparency International Corruption Perceptions Index 2025
Comprehensive Assessment: United Kingdom and United States
Executive Summary
The 2025 Corruption Perceptions Index reveals record-low scores for both the United Kingdom and United States. The UK dropped to 70/100 (20th place), its lowest score since 2012, while the USA fell to 64/100 (29th place), also a historic low. Both countries have fallen from the global anti-corruption leadership tier, now trailing countries like Lithuania, Barbados, and Uruguay.
Transparency International explicitly warns that this decline is "not a temporary blip" and risks becoming "a defining feature of political culture" in both nations.

Key Quotes from Daniel Bruce (Chief Executive, Transparency International UK)
"For three years running, the UK has been stuck at 20th place in the Corruption Perceptions Index with a score that continues to deteriorate. This persistent decline is not a temporary blip — it risks becoming a defining feature of our political culture."
"The data collection period for this year's index covers some of the highest spending political campaigning on record, alongside troubling reports of access-for-cash arrangements and questionable appointments processes. Unless we act decisively to tackle the corrupting influence of big money in politics and strengthen anti-corruption frameworks, these concerns will become the new normal."
"The UK government must demonstrate that it is serious about restoring integrity. That means taking bold action to remove big money from politics, delivering genuinely open government, and ending the cronyism that undermines public trust in our institutions."
"We are not tackling the root causes of corruption in our politics."

UK Government Response
"This government is committed to tackling corruption and protecting working peoples hard-earned money. Our anti-corruption strategy targets corrupt actors directly, cutting off their influence and strengthening the systems that protect our democracy. This strategy brings more corrupt individuals in the UK to justice and includes £15m of new funding for an expanded domestic corruption unit."

TI UK's Forward Assessment and Recommendations
Warning: Corruption concerns are "risking becoming embedded as the 'new normal'"
Assessment: Business as usual is "not enough to turn the corner"
Three key recommendations:
- Protect democracy by removing big money: Place a meaningful cap on donations; reduce campaign spending limits; increase transparency over the source of funds; strengthen the Electoral Commission
- Deliver open government: Extend transparency requirements to all lobbyists, requiring more detail about interactions (as in Canada, Germany, and the US)
- End cronyism in Parliament: End MPs holding second jobs; reform the process for making appointments to the Lords; remove those found engaged in serious misconduct

Key Quotes from TI Leadership
Maíra Martini (CEO, Transparency International):
"We are very concerned about the situation in the United States. This declining trend might continue."
"At a time of climate crisis, instability and polarisation, the world needs accountable leaders and independent institutions to protect the public interest more than ever — yet, too often, they are falling short."
Sources: CNN, Transparency International
Gary Kalman (Executive Director, Transparency International US):
"The use of enforcement discretion to politically determine winners and losers, and the selective loosening of market rules to favor politically connected actors, undermine core principles of the rule of law, fair competition, and anti-corruption. Anti-corruption laws should be there to serve the public interest, not be distorted to advance narrow political or economic interests."
"Perhaps most alarming is that these actions encourage leaders in other countries to further target and restrict independent voices, including advocates and journalists."
"Beyond the CPI findings, the temporary freeze and weakening of enforcement of the Foreign Corrupt Practices Act signal tolerance for corrupt business practices, while cuts to US aid for overseas civil society have weakened global anti-corruption efforts."

TI's Warning on Leadership Gap
Sources: Transparency International, The Guardian
What This Means for Global Anti-Corruption Leadership
The number of countries scoring above 80 has shrunk from 12 a decade ago to just 5 in 2025. This represents a 58% reduction in the number of countries considered to have strong anti-corruption frameworks.
The UK and US, traditionally seen as global leaders in governance standards, have now fallen to the middle tier of the index, undermining their ability to advocate for anti-corruption reforms internationally.

Section 6: Forward Warnings and Projections
United Kingdom
Risk: Corruption concerns becoming "embedded as the new normal"
Window for action: Business as usual "not enough to turn the corner"
Immediate pressure: Mandelson-Epstein scandal likely to fuel further deterioration in 2026
United States
Risk: Declining trend "might continue"
Data gap: 2025 developments not fully reflected; Trump's second presidency actions may further depress score in 2026
Global contagion: US actions encourage other countries to target independent voices
Global
Trend: Global average at 42, lowest in more than a decade
Clean governance club: Shrunk from 12 countries to 5 in a decade
Warning: "The world needs principled leaders and strong, independent institutions that act with integrity to protect the public interest. Yet, too often, we are seeing a failure of good governance and accountable leadership."
Conclusion
The 2025 Corruption Perceptions Index represents a watershed moment for both the United Kingdom and United States. After decades of global anti-corruption leadership, both nations have fallen to historic lows, undermining their moral authority and strategic position.
Transparency International's assessment is unambiguous: this is not a temporary decline, and without decisive action, corruption concerns risk becoming "a defining feature of political culture" in both countries.
The specific causes identified — donor capture, politicised enforcement, judicial independence concerns, and attacks on civil society — represent structural failures that will require comprehensive reform, not incremental adjustment.
With the global average at its lowest level in over a decade and the club of "clean" countries shrinking by 58%, the world is experiencing a profound crisis of anti-corruption leadership. The question now is whether the UK and US can reverse course before the damage becomes irreversible.
