Leading article: We could do with a few more dry eyes in the House Britain has often looked on inebriate MPs with indulgence, hence the many tales of encounters between boozy MPs and their detractors, often featuring Winston Churchill or Harold Wilson's deputy, George Brown, about whom the phrase '"tired and emotional" was invented.
