Salary scales have now been provisionally agreed, and although not public knowledge, many internally will testify that they are marginally better than the current SSP scales. This is purely down to the tax free element, which offers a win win situation for both parties.
I have also heard that a significant number of the first batch will come from the military cadets who were recently made redundant. These are high calibre applicants with a proven record, all they need to do now is pass the selection. Good luck guys!
