UK Match-Fixing Law: Lords Weigh Macolin Convention Ratification

The House of Lords International Agreements Committee is weighing whether the UK should finally ratify the Macolin Convention, the only legally binding international treaty against match-fixing, after a second evidence session on 14 July 2026 heard that corrupters, not just corrupted athletes, must be the target of prosecution. The UK signed the Council of Europe treaty in December 2018 but has never brought it into national law, and integrity experts told peers that full ratification would speed cross-border data sharing and help dismantle the criminal networks driving sports corruption.

Karen Moorhouse, chief executive of the International Tennis Integrity Agency (ITIA), used the hearing to reframe how match-fixing is prosecuted, arguing that players caught up in schemes are frequently victims of organised crime rather than the masterminds. Her evidence, alongside testimony from the Sports Betting Integrity Forum and the Gambling Commission, sharpened a debate that has run for years: the UK helped write the rules on sports integrity, yet sits among the signatories that have not turned signature into binding law.

What is the Macolin Convention and why does it matter?

The Macolin Convention is the only international treaty that legally binds countries to prevent, detect and punish the manipulation of sports competitions. Formally the Council of Europe Convention on the Manipulation of Sports Competitions, it was drafted in Macolin, Switzerland, opened for signature on 18 September 2014 and entered into force on 1 September 2019 once enough countries ratified it. It commits states to criminalise match-fixing, set up national platforms to share information between sports bodies, betting regulators and law enforcement, and cooperate across borders. You can read the full text on the Council of Europe website.

Has the UK ratified the Macolin Convention?

No. The UK has signed the Macolin Convention but has not ratified it. Then Minister for Sport and Civil Society Mims Davies signed on the UK's behalf on 6 December 2018, calling match-fixing "a real threat to the integrity of sport," but successive governments have not completed ratification into domestic law. That gap is exactly what the House of Lords International Agreements Committee is now scrutinising, hearing evidence on whether ratification would strengthen the UK's hand against sports corruption. The original signing announcement remains on GOV.UK.

What did Karen Moorhouse tell the House of Lords?

Moorhouse told peers that authorities must pursue the criminals who corrupt athletes, not only the athletes themselves. She argued that fixers deliberately target vulnerable competitors, then simply move on to new players once one is banned, meaning bans alone never break the chain.

"They have been corrupted by someone who's preyed on their vulnerability," Moorhouse said of players drawn into fixing, urging the committee to focus enforcement on the organisers behind manipulation schemes.

The ITIA is one of the busiest integrity bodies in world sport, and tennis has repeatedly featured among the sports with the highest volumes of suspicious betting activity, which is why Moorhouse's call to prosecute the "corrupters" carried weight with the panel that included Lord David Hannay.

Who else gave evidence to the committee?

The 14 July session heard from a panel of integrity and enforcement figures alongside Moorhouse. Nigel Mawer, co-chair of the Sports Betting Integrity Forum and a long-standing figure in snooker's governing body the WPBSA, and John Pierce, the Gambling Commission's director of enforcement and intelligence, set out how the UK currently detects and disrupts fixing. A week earlier, on 9 July 2026, the committee took evidence from Moses Swaibu, a former professional footballer jailed for 16 months in 2013 for his role in a match-fixing conspiracy and now chief executive of integrity firm GameChanger360, and Madalina Diaconu, a Swiss sports and gambling law specialist and associate professor at the University of Neuchatel.

How big is the match-fixing problem right now?

Suspicious betting activity is rising, not falling, on the leading global measures. The International Betting Integrity Association (IBIA) reported roughly 300 suspicious betting alerts across 16 sports in 2025, a 29 percent increase on the previous year, according to its annual integrity report covered by iGaming Business. Peers on the committee also pointed to a reported 92 percent rise in suspicious soccer matches flagged in Africa and noted that nine of the 16 clubs in the Chinese Super League began a recent season on negative points after bribery and match-fixing sanctions, an illustration of how deep the problem runs in some markets.

Why do experts say bans on players are not enough?

Because banning a fixed player removes a symptom, not the cause. The consistent message across both hearings was that organised crime, not opportunistic athletes, drives modern manipulation, and that criminal networks recover quickly when only the players are punished. Diaconu told the committee in the earlier session that "over the last 15 to 16 years, we have seen a tremendous increase in the infiltration of organised crime into match-fixing," framing the issue as a law-enforcement problem rather than a purely sporting one.

What did a convicted former fixer tell peers?

Moses Swaibu, who has since worked with the Football Association, the Premier League and FIFA on integrity, warned that the sheer scale of legal betting markets has handed criminals unprecedented opportunity. He argued that the UK's global standing in sport gives it unusual influence to set a standard others would follow.

"The UK is the home of football and sport; flying this flag at the highest level will help the rest of the world move forward," Swaibu told the committee, backing ratification.

How does the UK compare with other countries on Macolin?

The UK is one of a large group of signatories that has not ratified, and it is far from alone in the delay. The table below summarises where things stand.

Status	Detail
Treaty adopted	Drafted 2014, opened for signature 18 September 2014
Entered into force	1 September 2019
Signatories	43 European states plus Australia, Brazil and Morocco
UK signature	6 December 2018 (Mims Davies)
UK ratification	Not ratified as of July 2026
Notable holdout	Malta, citing concerns over its licensed betting operators

Why has Malta been a sticking point?

Malta has long resisted ratifying the Macolin Convention over how it defines illegal betting, a stance rooted in protecting its large base of licensed online operators. Because Malta hosts a significant share of Europe's igaming industry, its objection has slowed the treaty's momentum across the European Union and is frequently cited as a reason the framework has not achieved the universal buy-in its drafters intended. That tension between betting industry interests and integrity enforcement runs through the entire ratification debate.

What would ratification actually change in the UK?

Ratification would give the UK a binding legal framework for cross-border cooperation and data sharing, which witnesses said is the single biggest gap today. In practice it would formalise the exchange of intelligence between the Gambling Commission, sports governing bodies, betting operators and overseas authorities through a national platform, and strengthen the basis for prosecuting the organisers of fixing rather than only sanctioning athletes through sporting tribunals. Criminal prosecutions for match-fixing remain rare in the UK, and supporters argue Macolin would help close that enforcement gap.

How does this connect to wider betting integrity pressure?

The Macolin debate lands amid a broader global crackdown on betting-linked corruption and integrity risk. Regulators and law enforcement have escalated action across multiple fronts in 2026, from a high-profile NBA betting bribery case in the United States to Interpol's Operation First Light sweep against illegal gambling networks and a major World Cup betting crackdown in China. The same pressures are visible in elite sport itself, where players have spoken out about betting-related abuse. Against that backdrop, whether the UK ratifies a treaty it helped shape has become a test of how seriously it treats sports corruption.

What happens next?

The International Agreements Committee will weigh the evidence from its July sessions before reporting its conclusions and recommendations to the government, which is not bound to act but faces growing pressure to explain the eight-year gap between signature and ratification. There is no fixed statutory deadline, so the timing rests on political will. For operators, suppliers and sports bodies, ratification would signal a firmer UK stance on integrity data sharing and a shift toward prosecuting the networks behind manipulation rather than the players in front of them.
