The coompulsory spin training was dropped from the syllabus in the 90's. The logic was impecable but there was a lot of heated debate at the time. The argument was that there were around 8 spinning related deaths per annum in the UK. Of which around 6 happened as a result of spin training. By dropping the training requirement (and inserting incipient recovery technique training) you might see the non-training spin deaths rise from 2 to 4 but you'd see the traning related spin deaths of 6. A net reduction in lives lost.
I support the move as most of the non-training spin deaths were from either totally disorientated pilots in cloud or mishandling close to the ground and stalling - often whilst circling their house waving or taking pictures. From which spin recovery was impossible anyway due to lack of height.
