UK’s top gambling regulator has found its new top cop.

On Thursday, the UK Gambling Commission (UKGC) announced that Neil McArthur has been appointed as its news chief executive, effective immediately. McArthur’s appointment was made after “a thorough search and highly competitive process to recruit the role,” according to UKGC.

McArthur took over the CEO position on an interim basis following the abrupt resignation of Sarah Harrison in February. Harrison, who oversaw UKGC’s new willingness to back up its words with tough enforcement policies, stepped down to take a senior role with the Department of Business, Energy and Industrial Strategy.

McArthur is a qualified solicitor who has served as a general counsel for the UK gambling regulator since 2006 before he was promoted to executive director in August 2016. Before his UKGC gig, McArthur served as in-house lawyer for public groups including the Learning and Skills Council and the General Teaching Council for England.
