Is the tail wagging the dog here?

My mole tells me that the big SNP/Libdem budget pow-wow is tomorrow where these two strange bedfellows will hammer out their budget plans, such as they are.

I hear is that the SNP group have been told by their Holyrood associates to go in there and bang heads together to ensure that what ever else happens, Portobello High is in the budget even if thats the only school that is funded. If it is the only school on their budget slate then we will know who really is running the coalition and its neither of the groups that purport to be in charge...
