The chef, Tim Allen, convicted last Thursday of possessing images of child pornography, is to cease all connection and involvement with the Ballymaloe Cookery School, the Ballymaloe House Hotel and all other related businesses.
The announcement was made in a statement issued by the Allen family a short time ago.
In his first comment since his conviction, Tim Allen said that what he did was wrong and he would live with the shame of it for the rest of his life.
Middleton District Court in Cork substituted his nine-month suspended jail sentence for a 240-hour community service order, after Mr Allen agreed to make a €40,000 contribution to a charity.
Earlier today, Tánaiste Mary Harney confirmed that the Government is to change the law to allow the Director of Public Prosecutions to appeal against what it regards as lenient sentences imposed in the District Courts.
Ms Harney said that the Government had promised to do this in the Programme for Government, and was not taking this action as a result of the conviction last Thursday of the Ballymaloe chef, Tim Allen, for possessing images of child pornography.
