Leafing through a medical dictionary the other day, I came across the following entry.
Griffinism: a disease of political parties, it attacks their immune system, leaving them vulnerable to opportunistic infection by "industry experts", and other similar parasites. Treatment: carefully titrated doses of democratic reform, administered internally, under hospital supervision. Prognosis: often fatal due to its insidious onset but may be cured if correctly diagnosed, and treated in its early stages. Case study: British National Party, 2007-2010.
