Furthermore, the use of online technologies allows British citizens to communicate faster, easier and more conveniently than ever before with, with social networking sites allowing real-time interaction overcoming geographical and time constraints. There is limited research looking at the use of online communication by Member of Parliaments (MP) in their constituency role, which is surprising as the constituency responsibility of an MP has become of increasing importance in the last 50 years due social and political changes including heightened demands from citizens. Using an original field experiment, this thesis tests which method of communication is the most effective for constituents to use when contacting their local MP, with specific interest in their adoption and use of the social networking site Twitter. The research finds that the majority of MPs have a Twitter account; however theses Members tend to be young, on the left of the political spectrum and reside in marginal constituencies. Members do not appear to be using Twitter to correspond with constituents, although it is the fastest of the tools tested. Email had both the highest response rate and is most likely to provide the constituent with the information they requested, and is therefore the most effective medium for MP-constituent communication.Show less
