Between 2001 and 2004 our predecessor FaxYourMP.com published a league table of MP responsiveness data, measuring the proportion of users who said that they had heard something back from their MP after they had written to them.
In 2005 mySociety held off publishing an updated version of this data because we were busy totally rebuilding FaxYourMP as WriteToThem, adding all the UK’s 20,000+ other elected representatives, such as councillors and MSPs.
Note: During the period up to a General Election there are no MPs, by electoral law. We disabled WriteToThem’s facility for writing to MPs on 14th April, enabling it again a week after the election on 12th May.
