Labour MEP Nessa Childers has written to the European Parliament requesting that the commission cut off the EU pension of former Irish Commissioner Padraig Flynn.
Ms Childers said he was Ireland's European Commissioner until 1999 and would have a substantial pension arising from this time paid by European citizens.
She said the findings of the Mahon Tribunal yesterday in relation to Mr Flynn mean he had disgraced Ireland's good name in Europe, and therefore he should no longer receive his sizable pension.
Earlier in a statement: Padraig Flynn said: "During my lifetime of involvement in politics I have never sought nor have I ever received a corrupt payment.
"I absolutely reject any such finding of this Tribunal in that regard.
"It is not my intention to issue any further statement at this time."
