  Wikipedia is a major source of information providing a large variety of
content online, trusted by readers from around the world. Readers go to
Wikipedia to get reliable information about different subjects, one of the most
popular being living people, and especially politicians. While a lot is known
about the general usage and information consumption on Wikipedia, less is known
about the life-cycle and quality of Wikipedia articles in the context of
politics. The aim of this study is to quantify and qualify content production
and consumption for articles about politicians, with a specific focus on UK
Members of Parliament (MPs). First, we analyze spatio-temporal patterns of
readers' and editors' engagement with MPs' Wikipedia pages, finding huge peaks
of attention during election times, related to signs of engagement on other
social media (e.g. Twitter). Second, we quantify editors' polarisation and find
that most editors specialize in a specific party and choose specific news
outlets as references. Finally we observe that the average citation quality is
pretty high, with statements on 'Early life and career' missing citations most
often (18%).
