The £1.4 million was the money that Lavaflow "invested" (or as some might say paid to themselves).
Most of it was money they got from naive and unsuspecting investors (including G's mother-in-law) and not their own money - remember Mcfraud saying he remortaged his house when it was rented.
These investors were persuaded that the ground relocation was going to make them a lot of money or at least that it was what mr S charmed them into thinking. And they used a bent "accountant" with access to high net worth individuals to target potential investors.
My own view for what it is worth is that the ground relocation was a complete scam (they would still have gone ahead and made money from the Tattershall road site but they were not going to invest £6 million on a new stadium). It was never a serious undertaking but deflected everyone from the fact that you can make a lot of money in football if you do not pay your creditors.
