    "abstract": "The ${\\cal PT}$ symmetric version of the generalised Ginocchio potential, a\nmember of the general exactly solvable Natanzon potential class is analysed and\nits properties are compared with those of ${\\cal PT}$ symmetric potentials from\nthe more restricted shape-invariant class. It is found that the ${\\cal PT}$\nsymmetric generalised Ginocchio potential has a number of properties in common\nwith the latter potentials: it can be generated by an imaginary coordinate\nshift $x\\to x+{\\rm i}\\epsilon$; its states are characterised by the\nquasi-parity quantum number; the spontaneous breakdown of ${\\cal PT}$ symmetry\noccurs at the same time for all the energy levels; and it has two\nsupersymmetric partners which cease to be ${\\cal PT}$ symmetric when the ${\\cal\nPT}$ symmetry of the original potential is spontaneously broken.",
