Animal Farm is one of the most famous warnings ever written. Orwell's immortal satire - 'against Stalin' as he wrote to his French translator - can be read on many levels. With its piercing clarity and deceptively simple style it is no surprise that this novel is required reading for schoolchildren and politicians alike. This fable of the steadfast horses Boxer and Clover, the opportunistic pigs Snowball and Napoleon, and the deafening choir of sheep remains an unparalleled masterpiece. One reviewer wrote 'In a hundred years' time perhaps Animal Farm ... may simply be a fairy story: today it is a fairy story with a good deal of point.' Over sixty years on in the age of spin, it is more relevant than ever.
