When Ben Dunne famously misbehaved and then lost it in Florida, who’d have foreseen the outcome? The great and good brought low, their conceits laid bare. Yes, there were other triggers. But that was the seminal moment that undid the unholy nexus of politicians, planners and property speculators.

Two tribunals are operating under Judges Moriarty and Flood. The Ansbacher inspection has finished its work. At a combined cost to date of €37million, a whole edifice has come unstuck, slowly and surely. We have heard an extraordinary range of allegations and disclosures and a cast of heroes and villains has been paraded.

A great cleansing is under way.
