I was going to say 'calumny' but then I found out it didn't mean what I thought it meant i.e. general naughtiness, but instead means false accusation or slander or defamation.
Anyway. First of all it's the BBC accused of bias; now I find that even my polling station isn't immune: it has a definite tendency to lean to the right. This is obviously a deliberate attempt to affect the subconscious of the voters. Sending subliminal messages to our brains.
Well, it won't work on me!
P.S. I know it's an optical illusion but allow me the opportunity to use the word 'calumny'.
