Taoiseach Enda Kenny's leadership is to come under intense pressure next week as Fianna Fail takes a massive 11 point lead on Fine Gael in the latest opinion poll.
The widening gap in public support between Fine Gael and Fianna Fail will focus the spotlight on the Taoiseach as he faces into the second week of the latest Garda scandal.
Fine Gael is down two points to 21pc while Micheal Martin's party is up three points to 32pc. The poll comes as Mr Kenny seeks to explain why he and his Cabinet was not aware of sex abuse allegations made against Sgt Maurice McCabe when they discussed the Commission of Investigation tasked with examining allegations of a smear campaign against the whistleblower.
Mr Martin's personal satisfaction rating is up four points to 53pc, while Mr Kenny is up one point to just 30pc.
The Sunday Times/Behaviour and Attitudes poll also shows Sinn Fein is up two points to 19pc. The Labour Party is up one to 6pc, while the Independent Alliance is up one to 5pc. The Anti-Austerity Alliance/People Before Profit is down two points to 3pc. Social Democrats are up one to 2pc, the Green Party is down one point to 2pc and Workers Party is up one to 1pc.
Independent and others are down a massive seven points to 8pc.
