I don't know what discussions may or may not have taken place, but I do know that Wasps were aware of Ashley's interest way before all of this so I presume some dialogue may well have taken place (dependant on what the final outcome may be).
I also understand that the Freehold stipulates the land/stadium is for sporting use so if Ashley has bought the Lease, he would have to honour that.
As he is looking to build his new HO just up the road in Ansty, I presume that he'd want to keep the council on his side for any planning "issues" that might crop up at that site so offering a "sporting home" to those that want it would make sense to me.
However, we are talking business and pretty "big bucks" so common sense may not apply, but you would hope it would for everyone's sake.
After all the vast majority of the local (and wider) community and sports fans just want to enjoy their day out with their families and friends and be entertained.
