New Dáil footage has emerged showing Fianna Fáil TD Lisa Chambers casting votes on behalf of a colleague.
The Sunday Independent reports she recorded seven votes while sitting in party colleague Timmy Dooley's chair last January.
Deputy Dooley said he was in the chamber at the time with Dáil records also showing he was present in Leinster House.
It comes as an Oireachtas committee previously warned Deputy Chambers for voting on behalf of Fianna Fáil deputy leader Dara Calleary.
It also continues to investigate six votes recorded by TD Niall Collins on behalf of the Deputy Dooley.
