I think you have answered your own question. Medical politics! That also explains the choice of the difficult St.James's site. Harris is a light weight who may bluster but hasn't got what it takes to stand up to a relatively small group of consultants.So why is Holles street going ahead before a new maternity hospital at James? I suspect there is a lot of medical politics involved in these decisions but its interesting that no politicians are advocating prioritising a maternity hospital at James over Holles street, its not so long since they were howling about giving the nuns the new Holles street.
