If that’s the case then someone else needs to be in charge. Football managers get quickly sacked from roles when they do poorly, as do Government cabinet members. Seems bizarre at council executive level to keep someone still doing the same thing when they are clueless. It means nothing that they are head of an independent grouping.
Clr Phillips is great at keeping Penycae tidy with his voluntary group of people, dealing with litter, fly tipping and dog fouling – on a highly frequent basis. I know this is at village level, but if he knows a thing or 2 about keeping the place clean I’m sure there’s himself and plenty other councillors who can keep their local wards clean and tidy who would be able to do a better job as Environmental Lead or even just a special delegation towards town cleanliness.
