To confirm a couple of things other posters have put
a) Planning permission to add at a later date a second tier to the East Stand to increase the capacity to 40k was signed off when originally built (although would expect the council to invoke the park & ride facilities originally promised to be built)
b) Stadium is still owned by Teachers, with rent being paid back, so still circa £16m. A big if, but if we stayed in the Premiership for several consecutive seasons, MM does then intend to but the stadium from Teachers.
When considering areas of the country to cope with the influx of people for a sporting occasion, the fact Leicester has the Special Olympics this year, would also be factor in our favour.
2 separate arenas locally could also be offered to the clubs taking part, as the Tigers ground could be utilised
