Is The Amazing Mrs Pritchard coming back?

The Amazing Mrs Pritchard revolves around supermarket manager Ros Pritchard, who, angry with the state of British politics, stands for election as an independent candidate in her home town of Eatanswill, Yorkshire. She soon gains national attention and wins the general election, becoming Prime Minister. Over successive episodes, Ros's spontaneous approach to decision making and her promise never to deceive the electorate come under increasing pressure from the demands of government, media scrutiny, and partisan political struggles.
