So if we don't pay up on Tuesday

The HRMC will say we are trading insolvent just like Portsmouth.
Let's face it if the funds are not in place after all the fuss about the land deal.
The HRMC really do have a point.

Apparently we are paying something so it depends on how much we have.

If it is a token £100k we are in trouble, but closer to £1m would probably save us.
