SIR – “If you want to know your enemy sing his song” is a famous old saying that many socialists will be familiar with.

So I often look at the right-wing press finding its contents very revealing, for instance Iain Duncan Smith’s anger that jobless-related benefits are to rise in line with inflation, which is seen as a blow to his welfare later as the unemployment total rises ever upwards.

Beware, therefore, any crocodile tears coming from the Tory party.
