Angered at the lack of conviction by members of Parliament who seem to do nothing but squabble among themselves, Mrs. Ros Pritchard, a supermarket manageress in the Northen town of Eatanswill, decides to run for office herself, forming her own, independent party, the Purple Alliance, which is hugely attractive to women. To the bemusement of her husband, Ros eventually becomes Prime Minister, with Catherine Walker, the Tory sent to oppose her as her deputy.
