Taoiseach Micheál Martin confirmed the news on Monday.
Dara Calleary has resigned as Deputy Leader of Fianna Fáil in the wake of controversy surrounding his attendance at an Oireachtas Golf Society event in Clifden last week.
The Mayo TD resigned his position as Minister for Agriculture on Friday and Taoiseach Micheál Martin confirmed on Monday that he has also resigned his position as Deputy Leader of the Fianna Fáil party.
Confirming the news while speaking to Claire Byrne on
RTÉ Radio One on Monday morning, Martin said: "He (Calleary) is very, very sorry for what happened."
In a statement on Thursday evening preceding his resignation as Minister for Agriculture on Friday, Calleary said: “Last night I attended a function I committed to a number of weeks ago, having been asked to pay tribute to a person I respected and admired greatly.
"In light of the updated public health guidance this week I should not have attended the event.
"I wish to apologise unreservedly to the public, from whom we are asking quite a lot at this difficult time. I also offer this apology and my sincere regret to my government colleagues.”
