The appointment of Phil Walker as interim chief executive of the UK National Lottery operator has come under political scrutiny, with concerns raised over his past record in the gambling sector and his recent involvement with a major adult gaming center operator.

Allwyn UK, which holds the National Lottery license until 2034, announced that Walker will replace outgoing chief executive Andria Vidler on an interim basis from 7 September. The company has described the appointment as an opportunity to bring extensive industry experience into the organization at a time of increasing competition.

However, the decision has prompted questions from lawmakers who argue that the National Lottery occupies a distinctive position within British public life and should be held to particularly high standards when selecting senior leadership.

Labour MP Dawn Butler and Conservative MP Iain Duncan Smith have written to the Gambling Commission expressing concerns about Walker’s suitability for the role. In their correspondence, they said they were “deeply concerned” by the appointment and sought clarification regarding his previous regulatory history and his links to the adult gaming center sector.

Much of the scrutiny centers on Walker’s time at William Hill, where he spent six years in a number of senior management positions, including UK and Ireland Managing Director, Chief Commercial Officer and Online Managing Director.

During that period, three William Hill businesses were found to have committed significant anti-money laundering and social responsibility breaches. In March 2023, the Gambling Commission imposed a record £19.2 million regulatory settlement on the operator.

At the time, Gambling Commission chief executive Andrew Rhodes described the failings as “widespread and alarming”, with the regulator reportedly considering the suspension of William Hill’s operating license.

Investigators found several cases in which customers were able to gamble substantial sums without adequate checks. One online customer deposited and lost £70,134 within a month, while another retail customer staked £276,942 and lost £24,395 over a two-month period without appropriate source-of-funds verification.

The matter did not end with the corporate penalty. In May 2024, the Gambling Commission issued Walker with a formal warning after reviewing his Personal Management License. The regulator concluded that between May 2020 and October 2021 he had failed to take all reasonable steps to prevent breaches of license conditions relating to anti-money laundering requirements, terrorist financing controls and customer interaction obligations.

The regulator did not suspend or revoke his license and noted that Walker had been “cooperative, open and transparent” throughout its engagement with him.

In their letter, Butler and Duncan Smith asked the Gambling Commission to “explain what consideration, if any, was given to this history when assessing his suitability for his present position”.

A Gambling Commission spokesperson declined to comment on the appointment, stating: “We would not publicly comment on an operator’s personnel decisions.”

Questions Raised Over Game Nation Involvement

Beyond his William Hill tenure, MPs have also focused on Walker’s role as a non-executive director of City Gaming, the company behind Game Nation, one of the UK’s largest adult gaming centre chains.

Adult gaming centers, often referred to by critics as “slot farms,” typically operate around the clock and contain large numbers of slot machines. The sector has attracted increasing attention from politicians and local authorities amid concerns about gambling-related harm and the concentration of such venues in certain communities.

When Walker joined City Gaming last year, he said he was excited to “develop and grow the company over the coming years”.

The comment has attracted attention as policymakers examine measures aimed at tightening regulations governing adult gaming centers. Former Greater Manchester mayor Andy Burnham has been among the most prominent critics of the sector, accusing operators of “targeting some of the most vulnerable in our communities”.

Companies House filings reportedly indicate that Walker may have earned more than £50,000 through his non-executive position at Game Nation. The company has since confirmed that he will step back from the role from 1 September while serving as interim chief executive of Allwyn.

Jackie Olden, a campaigner whose mother lost significant sums gambling in adult gaming centers, also questioned the appointment.

“It’s awful that someone heavily involved with 24-hour slot farms that destroy families and communities can run the country’s biggest public sector contract,” she said, according to The Guardian.

Allwyn Defends Selection as Lottery Governance Examined

Allwyn has publicly backed its decision, arguing that Walker brings experience that will help guide the National Lottery through its next stage of development.

A company spokesperson said: “As we navigate an increasingly competitive environment, Phil Walker brings valuable operational, digital and marketing experience alongside a significant understanding of our operating landscape. His appointment will help deliver the next stage of growth and innovation of the national lottery, and we look forward to welcoming Phil to the role of interim CEO.”

The company has also highlighted that Walker retained his personal license following the Gambling Commission’s action, pointing to the regulator’s conclusion that he remained fit to work within the gambling industry.

The debate has also drawn attention to the National Lottery’s distinct regulatory framework. Unlike conventional gambling operators, the Lottery operates under a dedicated license overseen by the Gambling Commission and is required to generate funding for charitable and public-interest causes across the UK.

Under the terms of the Fourth National Lottery license, Allwyn must ensure that those managing the business satisfy “Fit and Proper Requirements”. The Gambling Commission also plays a role in assessing whether individuals involved in operating the Lottery meet those standards.

Industry observers note that while retaining a personal management license may satisfy regulatory requirements for commercial gambling operators, leadership of the National Lottery carries additional public expectations because of its role in distributing billions of pounds to good causes.
