The founder and former executive chairman of health software group iSOFT Group , Gary Cohen , has hit back at the company’s key shareholder, ­Oceania Capital Partners , saying it was unjustly trying to rush through a sale of the company to US outsourcer Computer Sciences Corp.

Mr Cohen told The Australian Financial Review he had been approached by a number of alternative prospective buyers, and was entitled to stop OCP selling its stake while the alternatives were pursued.
