Simon Coveney insists he was not lobbied by Katherine Zappone for a government appointed job at the United Nations.
The Foreign Affairs Minister will appear before an Oireachtas Committee later to take questions on his attempts to put Zappone forward for the position of Special Envoy for freedom of opinion and expression.
Mr Coveney will tell the committee Katherine Zappone reached out to him last summer and offered to help "in any way she could" at the UN.
The pair spoke again in February, and Simon Coveney then asked his Secretary General whether Zappone "could be of any use" to the Irish team in New York.
