'New politics', crisis effects and format effects: a comparative study of hostility and positivity in exchanges between leaders during UK Prime Minister's questions and Scottish and Welsh First Minister's questions

Existing research on party leader questioning in legislatures usually focuses on single case studies, less-than-ideal behaviours across leaders, and often post-election periods. Our article compares hostility and positivity in behaviours across three parliaments and, because of the COVID-19 crisis, across different time periods and modes of operation (live, hybrid, and online) while controlling for the same leaders. Using content analysis at the sentence level (N?=?3554), our data contrast parliamentary leader hostility and positivity levels in the UK, Scottish, and Welsh Parliaments across three time periods: pre-COVID-19, initial, and lockdown COVID-19. Findings for positivity are mixed, but for hostility, we find that while the initial shock of the COVID-19 crisis suppressed hostility, Westminster has higher ratios of hostility across all three time periods, and that format of operation has little effect on behaviour. Findings suggest less hostility in Scotland and Wales than in Westminster adding possible weight to ?new politics? arguments.
