Agritculture Minister Dara Calleary has given his resignation to the Taoiseach Micheal Martin.
He apologised last night for going to a golf event attended by 80 people that broke Covid 19 guidelines.
The minister admitted he shouldn't have gone to the Oireachtas Golf Society dinner at a hotel in Clifden, Co. Galway on Wednesday.
The government's guidelines state only six people can attend indoor gatherings - with some exceptions for up to 50 people.
