Scholars of rhetoric and parliaments have been slow to recognise this shift and its political implications. The book analyses the rhetoric of Westminster-related writings from late 18th century to WWII among scholars and others outsiders in contrast to parliamentary insiders (officials, journalists, members). A special attention is given to John Stuart Mill and Walter Bagehot as the most prominent British parliamentary theorists and to cases studies on actual parliamentary debates. With its procedures and ways of dealing time the Westminster-style parliament is an exemplary political assembly of debating pro et contra.
