Its just business - wrecking Fishguard is the cheap option
Amputating Fishguard's Market Square big roundabout severely disrupted the town's social life and, thereby, seriously impacted the commercial viability of its market town status, all of which rebounded to further undermine social cohesion, resulting in a hostile empty vessel takeover of The Square - much reported on in the local press.
Ergo, with local retailers' balance sheets and future prospects severely undermined, the threatened construction of a large, big league player's, in-town supermarket, on the site of the Council School, was the inevitable kiss of death for adjacent retailers: butchers, greengrocers, newsagents, bakers, and so forth.
This promise of assured degenerated cash-flow oblivion was the catalyst to ignite a cascading collapse of already, and deliberately, sabotaged business confidence, which, crystallized in a mass evacuation of shoppers and tourists as retailer after retailer developed and executed an exit strategy ... abandoning ship, so to speak.
Fishguard had become RMS Titanic: "As she goes down by the head, the water will spill over the tops of the bulkheads at E deck from one to the next. Back and back. There's no stopping it". (Mr. Andrews: Titanic,1997)
Its hardly rocket science: the inability of Fishguard to trade as a market town is cos its trapped inside an imploded 1997 "vision" designed to wreck it.
The codename for this vision became "Regeneration".
