Nick Mackenzie has been announced as the successor to Greene King chief executive Rooney Anand.
Anand will leave the brewer and pub company in April, after 14 years at the helm, to join the Casual Dining Group as chairman.
Mackenzie will join Greene King from Merlin Entertainments, where he was responsible for the Midway portfolio of attractions including Madame Tussauds, the London Eye and Sea Life aquariums.
He is also an independent non-executive director of pub company Daniel Thwaites, a role he will relinquish before taking up his position at Greene King on 1 May.
Commenting on the appointment, Greene King chairman Philip Yea said: "After a comprehensive search we feel that Nick's broad experience and track record at one of the world's leading leisure businesses as well as his knowledge of the pub business, both early in his career and more recently as a non-executive, make him the best candidate to lead Greene King through its next phase. We are looking forward to Nick taking up his role when Rooney steps down at the end of the current financial year."
Mackenzie added: "Greene King is a very strong business with a great portfolio of pubs and beer brands and a real commitment to its customers, staff and shareholders. I am looking forward to working with my new colleagues to deliver on our vision to be the best pub company and brewer in Britain."Get The Caterer every week on your smartphone, tablet, or even in good old-fashioned hard copy (or all three!).
