They frequently grouped right-leaning suburban areas within urban historic centres and more modern, urban left-leaning areas such as the bulk of Slough. This ostensibly amounted to nationwide gerrymandering or homogenisation to install a greater number safe seats at the expense of marginal seats however also reflected the majority of social associations of people in each area.
