Unfortunately I read today that the stores, Oasis and Warehouse are going into administration.
Also Laura Ashley are closing.

The present situation has hastened things, but they were on thin ice before all of this. I fear that our present problems will be the catalyst (or excuse!) for many more businesses to cease trading.

I suppose that the internet is another underlying factor here, in that online shopping is the shape of things to come. (Though I sincerely hope not). With these small businesses, I think you would need to do a detailed analysis of what kind of businesses are , because I suspect the niche ones will survive anyway.

Rising rent and rates, falling foot-fall few will be immune. I even know of a couple of specialised model shops that have closed their doors.

Some specialist type shops might be able to adapt to an online model, but I suspect many will only be shorterm until the present owners retire.

I suspect that high-end clothes shops might survive and the more upmarket jewellers, but for most, the future must be looking very bleak.

Well, that's the Leamington & Stratford branches of Debenhams officially gone: https://www.bbc.co.uk/news/business-52330268

The county will soon be bereft of Debenhams branches: https://www.stratford-herald.com/109211-housing-plan-proposed-landmark-southam-restaurant.html

Very difficult times ahead, Lex.

There are. One independent shop where I live seems to have called it a day - a 'to let' sign has appeared in the window.
