Fergus Finlay: Labour's existence is deeply threatened

TD Ivana Bacik (left) listens to former Labour Party leader Alan Kelly's resignation speech outside Leinster House.
This is existential. Which is to say, it’s about the existence of my party. The Labour Party. Ireland’s oldest political party.
I don’t know what happened to Alan Kelly and why it happened. I know there was deepening unease about the direction of the party, but I don’t know what actually triggered his colleagues to go to him the way they did.
