Who is new Green Party TD Joe O’Brien?

Calm, reserved, hardworking, very thorough and “not a man to pick up a megaphone” to deal with a challenge is how a colleague describes newly elected Green Party TD for Dublin Fingal Joe O’Brien.

It is the second victory in a year for the 42-year-old Skerries-based politician. He was elected to Fingal County Council in the May local elections on his second attempt and his Dáil byelection win also comes on a second attempt after a run in the 2016 general election.

The Dublin Fingal win offers a northside balance in the Dáil for the Green Party, whose leader Eamon Ryan and deputy leader Catherine Martin are both southsiders.

Married with three children, aged two, seven and nine, Mr O'Brien is originally from rural Grenagh, halfway between Mallow and Cork city.
