Allwyn UK, the company currently licensed to operate the National Lottery until 2034, announced last week that Phil Walker will serve as its interim chief executive. Walker, who previously led the UK and Ireland divisions of the betting firm William Hill, replaces outgoing CEO Andria Vidler.

The appointment has drawn criticism from some members of Parliament, who have formally contacted the Gambling Commission to express concerns. The scrutiny centers on Walker’s professional background, specifically his involvement in the 24-hour slot machine sector. This sector has been previously identified by the Prime Minister as a negative influence on British high streets.

While Allwyn UK has framed the appointment as a leadership transition, the involvement of the industry regulator suggests that the selection process is being treated with significant caution. It remains unclear whether Walker is a candidate for the permanent role or if his tenure will be strictly temporary. The Gambling Commission has not yet issued a public response regarding the specific concerns raised by the MPs, though the inquiry highlights ongoing tensions between the regulation of the National Lottery and the broader commercial gambling industry.
