In this episode I use the famous Enoch Powell quote about political lives ending in failure "unless they are cut off in midstream at a happy juncture" to ask if any of the three leaders will know when to go?

I consider Ireland's three main party leaders through Powell's lens: is Mary Lou McDonald in trouble as leader, is Micheál Martin now delaying the inevitable; and is Simon Harris, racing toward a juncture he may never reach.

Does any party have a succession plan... or even see the merit of one?
