David Maddox: More budget latest

If anything sums up the pressure mounting on Green leader Patrick Harvie then the sight of him eating his soup alone in the canteen with a Newsnight camera pointed a few inches above his bald pate does it. It underlines that his vote and that of his colleague Robin Harper will be crucial. To be fair on Mr Harvie he somehow managed to pretend the camera was not there. Cool under pressure.
But the emotions are beginning to show in other parties. Labour are obviously nervous that this budget may fall. Their group meeting at 12.30pm confirmed that they will vote against and they are busily trying to make sure they are not blamed for the ensuing chaos that will follow a defeat for the Scottish Government.
One Labour spin doctor has just spent most of lunchtime briefing me that SNP Finance Secretary John Swinney may be "deliberately trying to sabotage the budget" in the hope it will damage oppositon parties.
However, if the smiles on SNP faces and their spin doctors is an indicator to go by, then all may be well and a deal may have finally been struck with the Greens, not that they are letting on.
John Swinney will get to his feet to start the budget debate in just under 45 minutes. We will hopefully know then what is happening before the big vote at 5pm.
