I see Torquay are to enter administration today. I hope they survive, but it shows how precarious a position many clubs are. I remember watching that amazing 6-5 away victory in the second lockdown November 2020. I was also amazed they took over 400 fans to Dorking one Tuesday night last year. Southend have also had financial difficulties and a 10 point deduction this year, but sale of club supposed to be finalised this month.
A number of other clubs have gone bust this year, and have had their records expunged:
Marske United (Northern Premier League - Step 3, non league system)
Nuneaton Borough (Southern Premier Central - Step 3)
East Thurrock United (Isthmian League North - Step 4)
Hamworthy United (Southern League South - Step 4)
Have not checked below Step 4 but a lot of teams for one season!
