Ann Lim-Chaplain, publisher of Prestige Hong Kong, confirmed the news.
Ellul will head the monthly's design team in Hong Kong. Sources close to the news revealed Ellul quit the SCMP despite being given a promotion and a substantial pay rise in the last six months.
Post magazine has been without an editor-in-chief since Daniel Jeffreys departed in August 2010. Jeffreys, Ellul and former Post-staffer Angela Ho won a Society for News Design Award of Excellence for Post Magazine in 2010.
Ho left the SCMP to take Darren Long's job as art director at Prestige after he left to become creative director of Hong Kong Tatler. Ho resigned two months ago and Ellul now takes her job. Long, who lasted less than a month at Tatler, is now at Eight Custom Media.
"Steve's departure is a massive loss for the SCMP but a huge gain for Prestige,” a source close to this news said.
Prestige Hong Kong is a monthly luxury lifestyle and high society magazine published in Hong Kong by CR Media.
