Norwich North MP Ian Gibson was a little unfortunate when comments he made about the prevalence of diabetes in Norfolk were taken as a slur on his constituents.
Here's a good one. Labour council candidate Bill Lees had this to say about the inhabitants of the Birmingham suburb of Kings Heath.
"...legions of plug ugly, baseball-capped and ski-panted mingers from Kings Heath..."
Source. Bill is standing for election in the ward of Moseley and Kings Heath! Rather than apologising he is going with the context line. Has anyone got any similar examples of politicians insulting their electorate?
