You say that you've taken a different approach to the UK Government, but the remit letter that you've sent mirrors that of the UK Government exactly in emphasising affordability. You also define what affordability means—the amount that you, as a Government, can afford to pay—because you say in the letter:

'In the absence of increased UK Government funding, any changes to NHS staff’s terms and conditions will need to come from existing budgets.'

The problem is that that isn't true, as you could increase income taxes, which would mean that you could afford a fairer pay offer. Why didn't you include that option for the pay review body to consider, if this is a genuinely independent process?
