Aggressive/intrusive behaviours, harassment and stalking of members of the United Kingdom parliament: a prevalence study and cross-national comparison

Politicians suffer intrusive and aggressive behaviours from members of the public, often lone actors fixated on personal grievances. Few explorations of intrusive behaviours towards politicians have been published; their results are not directly comparable. We surveyed intrusive/aggressive behaviours towards UK members of parliament (MPs); our survey instrument was then administered to MPs at three other parliaments (Queensland, New Zealand, and Norway), providing a cross-national, four-site comparison. 239 MPs completed the UK survey. This 38% response rate produced prevalence rates remarkably similar to the other sites, New Zealand having an 84% response rate. 81% of UK MPs had experienced one or more of the 12 behaviours specified, the mean being five. 18% had been subject to attack/attempted attack, 42% to threats to harm and 22% to property damage. In 53% of respondents, experiences met definitions of stalking or harassment. This has implications for the provision of risk assessment and management.
