Phil Walker, former executive at William Hill and 888, temporarily takes the helm at Allwyn UK after Andria Vidler's resignation, who led the technological and commercial transition at The National Lottery.

Key Takeaways
- Andria Vidler leaves the leadership of Allwyn UK and Phil Walker takes over as interim CEO.
- The transition comes after a £450 million technological update at The National Lottery.
- Phil Walker, with experience at William Hill and 888, will guide the entity during the search for a permanent successor.

Allwyn UK, operator of The National Lottery, confirmed the departure of its CEO Andria Vidler and the provisional appointment of Phil Walker, former head of William Hill and 888, as interim CEO. Vidler will leave the position following an agreement with the chairman of the British subsidiary, Justin King, although she will continue in advisory functions until the end of October to ensure a smooth transition. Walker takes control while Allwyn searches for a permanent replacement.
Leadership Transition at Allwyn UK: Details of the Change
Andria Vidler's departure comes less than a year after she assumed leadership of Allwyn UK on October 1, 2023. During her tenure, she led the migration of 11.8 million player accounts to a new platform as part of a technological upgrade valued at £450 million for The National Lottery. Additionally, she coordinated a comprehensive modernization of the retail points of sale for the lottery.
Vidler was appointed in anticipation of Allwyn's takeover of the fourth national lottery license period in February 2024, after winning the tender led by the Gambling Commission in 2022. Allwyn UK thus replaced Camelot Group as the official license holder of The National Lottery in the UK.
“It has been a huge privilege to lead Allwyn UK through such an important period for The National Lottery,” noted Vidler in the company’s statement.
Phil Walker's Background and Industry Context
Phil Walker, who recently left his position as Chief Commercial Officer at 888 in April 2024, now takes on the interim leadership of Allwyn UK. Walker joined William Hill in 2019 as Managing Director Online after his time at the Gibraltar Stock Exchange and subsequently broadened his responsibility as General Manager for the UK in 2020 and for Ireland in 2023. Then, in July of that year, he became Chief Commercial Officer following the integration of William Hill into 888, resulting from the operator’s acquisition of non-US assets in 2022.
Since his departure from evoke (the new trading name of 888 and William Hill), Walker has worked as a sector consultant and as a non-executive advisor at City Gaming Limited. From Allwyn UK, he highlighted the importance of The National Lottery's role in the British community by saying:
“I am excited and proud to be taking up the baton from Andria and joining such a vital national institution at this important stage of its growth journey,” commented Walker on his appointment.
Recent Changes and Renovations at The National Lottery
Vidler's leadership transition coincides with other internal changes, such as the resignation earlier this month of Chris Lyman, Chief Operating Officer of Allwyn UK and a key figure in the technological migration process for The National Lottery. At the same time, Allwyn UK recently redesigned the Lotto format and introduced Powerball in the UK for the first time, expanding the national gaming offering.
During Vidler and Lyman's management, Allwyn faced legal challenges from Sir Richard Desmond and The New Lottery Company, who questioned the licensing allocation process led by the Gambling Commission. However, both the High Court and the Court of Appeal ruled in favor of the Gambling Commission in April and July 2024 respectively, supporting Allwyn's position as the official operator.
Future Perspectives and Operational Continuity for Allwyn UK
Vidler, with previous experience at EMI, emphasized that the transformation of The National Lottery is a long-distance race. In her farewell, she acknowledged the team’s contribution over three years to strengthen the institution's capacity to raise funds for social causes in the UK.
Phil Walker's experience, coupled with his commercial approach and knowledge of the betting and lottery sector, will be key to maintaining operational continuity during the selection process for the next permanent CEO and ensuring that The National Lottery continues to be a leading platform for raising funds for the British community.
The management of executive talent and recent appointments at Allwyn UK reflect the dynamism of the B2B lottery and betting sector in the British and European markets.
