While this may be good news for the local butchers, green grocers, etc, this will have have a huge negative impact on the regrowth of the economy and will hurt the pound massively. Consumer spending is obviously still very fragile, but this will tip it over the edge.
Tesco going belly up is a drop in the ocean. UK GDP is 2.5 trillion, 272~ billion of that is consumer spending. All that will happen if they don't recover is that their marketshare will be split amongst the rest.
I'm going to throw a wild bet out there and say Walmart buys Tesco and merges it with Asda.
