i think er it's got to be er linked certainly to the rate of inflation, er and in some way linked to the way that the fire service er has their pay formula, and they're actually linked to 25% of the top 25% of schooled manual workers, er we'd be looking at some sort of deal like that, or if it wasn't er tied up with percentage rates i think we need, definitely need an independent pay review body for the ambulance service.
