Police Scotland has cancelled plans to take on 200 new recruits in January as it tries to save money in the face of a £19m projected overspend.
The force is also redeploying staff from the Scottish Police College at Tulliallan, Fife, to back up frontline officers during the busy Christmas and New Year period.
All college training between December and January has been called off.
A senior officer said “hard choices” had to be made due to budget pressures.
But the Scottish Police Federation (SPF), which represents rank and file officers, described the decision as “shocking”.
No offers to candidates for the postponed intake of probationers – which was scheduled for 8 January – had yet been made and force confirmed the application process would continue for 2024.
