Having listened to those three clips all I hear is quotes of difficulties and expense imposed by local and central government.
Lack of footfall caused by parking restrictions/expense and lack of disposable income, coupled to energy and utility costs, business rates and taxation and rent. And although there's no reference made to it, you can certainly add in transport and shipping costs of retail goods.
Retail is an exceptionally difficult area to be in on this island, now and for the foreseeable future, those in it have nothing but sympathy from me. Government is crushing the life out of it on this Island.
