Allwyn UK, the operator of the UK National Lottery, announced that Chief Executive Andria Vidler will step down in September 2026. Vidler, who oversaw a £450 million technological upgrade, will remain in an advisory capacity through October to assist with the transition.

Phil Walker, a former executive at William Hill and 888, has been named interim CEO, effective September 7, 2026. His appointment has faced scrutiny from Members of Parliament, including Dawn Butler and Iain Duncan Smith, who have requested that the Gambling Commission review his suitability for the role.

Concerns raised by critics involve Walker’s background in the gambling industry and a previous £19.2 million fine imposed on William Hill for social responsibility and anti-money laundering violations during his tenure there. In response to the appointment, Walker will resign from his position on the board of Game Nation.
