Question: Who acted as the Mayoress of fictional Weatherfield and Rovers Return Inn in an ITV soap opera?
Context: Elizabeth "Betty" Williams (also Preston and Turpin) is a fictional character from the ITV soap opera, "Coronation Street", portrayed by former music hall star Betty Driver.  Driver was cast as Betty in 1969, after first auditioning for the role of Hilda Ogden, which was given to Jean Alexander.  The character arrived in "Coronation Street" to help her sister Maggie Cooke run the corner shop, and has since had a number of storylines which have seen her become twice widowed, and mother to an illegitimate son.

Much of Weatherfield has been seen by viewers throughout the years, though the primary focus from the viewer's perspective is the Coronation Street, a cobbled street where many of the programme's characters live.  Weatherfield areas are often shot on location around Manchester, as its filming studios, the Granada Studios complex on Quay Street in Manchester city centre (closed 2013) and its new set MediaCityUK in Salford Quays (opened 2014), only house the outdoor sets of Coronation Street and its immediate surrounding streets.

The Woolpack is a fictional public house on the popular ITV soap opera "Emmerdale".  Its sign is a wool bale, a popular symbol in sheep-rearing country.  It has played host to many of the soap's storylines and is the focus of the programme.  It is the second oldest TV soap pub, opening its doors in October 1972 and being preceded by The Rovers Return Inn which opened in December 1960 and succeeded by The Queen Victoria which opened in February 1985.  The Woolpack is the only soap pub to have changed locations as part of a story-line.  In 1976, the original Woolpack was found to be suffering from subsidence.  Another building was bought by landlords Amos Brearly and Henry Wilks and made its debut as The Woolpack later the same year.  This was to cover "Emmerdale Farm"'s move from Arncliffe to Esholt for location filming.
