Mr Banks, 61, one of Westminster's most colourful characters, formally announced his resignation to members last night. "I've gone 60 years of age and feel I have got a bit stale after more than 20 years as the local MP," he said. "I'm getting jaded and someone younger and more enthusiastic should now be given the chance." His decision infuriated members because Mr Banks stood for reselection only a few months ago and promised to serve for another full Parliament.
