Vannozzi, who joined Haymarket Network just over a year ago, will not be replaced. It is not known if Vannozzi, who reported to Haymarket Network managing director Andrew Taplin, has a job to go to.
New business will now be handled by Taplin, director of sport division Cormac Bourne, and editorial director Simon Kanter. The group publishes Sky Sports Magazine and Sony Magazine.
Previously, Vannozzi spent five years at News International-owned News Magazines and five years at The National Magazine Company.
In December, Taplin replaced Juliet Slot, managing director of Haymarket Network, who left to set up a specialist sports business and marketing consultancy.
