The Agriculture Minister described the disclosure as a 'flagrant breach' of criminal law.
GSOC has been asked to investigate claims a Garda member was involved in leaking information on Barry Cowen's drink driving ban.
It follows a statement in which the Agriculture Minister described the disclosure as a 'flagrant breach' of criminal law.
Last week it was revealed Minister Cowen was banned from driving in 2016 after being caught over the limit travelling from Dublin to Offaly.
Political correspondent with Independent News and Media, Hugh O'Connell, says the Minister will now face further examination about the incident:
