Taoiseach Enda Kenny has said that the days of "getting away with it" are over for corrupt politicians.
Mr Kenny was speaking at the MacGill Summer School in Glenties, Co Donegal this evening.
He said that there is now an effective ban on corporate donations above €200, unless corporate donors register with the Standards in Public Office.
The anonymous donation threshold is now down to €100.
Mr Kenny said there will be no more doubt and no more suspicion about the relationship between business and politics.
Fianna Fáil Senator Averil Power had earlier called for an independent watchdog for public representatives with the power to disqualify them from office.
The Taoiseach said that since the Government had come to power it has been developing direct action to tackle corruption.
He said Minister for Justice Alan Shatter is working on innovative legislation that will include provisions for the conviction of ministers, TDs and civil servants.
If convicted of a corruption offence, Oireachtas members could be subject of a court order to forfeit their office and be excluded from seeking office again for up to ten years.
