The UK’s top gambling regulator is looking for a new top cop after its current leader abruptly announced her exit.

On Thursday, the UK Gambling Commission (UKGC) announced that chief executive Sarah Harrison would be stepping down at the end of February to take a senior role with the Department of Business, Energy and Industrial Strategy.

The UKGC said the search for Harrison’s replacement was already underway, with chief counsel Neil McArthur agreeing to serve as interim CEO upon Harrison’s departure until a permanent candidate can be identified.

Harrison who became the UK gambling industry’s overseer in June 2015, issued a statement saying she was proud of what the UKGC had accomplished during her tenure, and expressed confidence that the regulator’s new strategy would “continue to make gambling in Britain fairer and safer.”
