A Sligo-Leitrim TD is calling for a banking inquiry-style investigation into what happened at Davy Stockbrokers.

Fianna Fail's Marc MacSharry made the call for a full investigation at the parliamentary party meeting last night and was supported by the chair of the Oireachtas Finance Committee John McGuinness.

Davy was fined over 4 million euro last week over a conflict of interest by 16 staff in relation to a bond deal.

Deputy MacSharry, who's a member of the public accounts committee, says the 16 people involved in the controversial bond deal need to be held to account.
