So, my point absolutely stands, which is that there is no hard-and-fast rule for strokes, neither in England nor in Wales. 

So, the McClelland review, which prompted the change to the clinical model response highlighted that the Welsh ambulance service has been subject to more reviews than any other part of the NHS in Wales and that this scrutiny contributes to the issues that the organisation faces. It concluded that a constant cycle of reviews can be disruptive, counterproductive and likely to have little chance of significant improvement for patients. 

The amber review undertaken in 2018 carried out by clinicians, found no clinical evidence to support the recategorisation of stroke calls into the red category as a whole. It would not be justified for yet another review of the ambulance service to prompt a change until there's a body of evidence to support such a change.
