Taoiseach Enda Kenny said he decided to call off a planned Fine Gael event to mark its first year in power as he felt it was not appropriate.
The photocall had been scheduled to take place today and was to feature Fine Gael members highlighting the party's achievements since it came to office.
Speaking at the Custom House for the launch of the 'Succeed in Ireland' initiative, Mr Kenny said he only became aware of the plan this morning and it was then that he decided to cancel it.
On RTÉ's Morning Ireland this morning, Labour Minister Pat Rabbitte criticised the planned event as "silly".
Minister for Health and Fine Gael’s deputy leader Dr James Reilly also came out against it after the cancellation and said he had not been consulted about it.
Speaking at a health conference in Croke Park, Minister Reilly said there were a lot of challenges facing the Government and the idea of a party came from over-enthusiastic backroom staff.
Fine Gael said: "It was presumed that the Labour Party would be planning an event, similar to the one scheduled by Fine Gael, to mark the Party's first year in Government.
''When it was discovered that this was not the case, it was deemed inappropriate to proceed.
"Much progress has been made in our first year in office but we realise that a difficult road still lies ahead."
