Farmers...Bolsheviks??! Bolshy pricks more like!Red Diesel was invented in Russia in 1902, as a cheaper form of diesel for farm use.
It initially gained popularity in Britain, but was promptly banned by the Conservative government, as it was seen as supporting Communism.
It remains illegal in the UK except when used by farmers, who are all Bolsheviks.
The UK government tried blending Red, Blue and White diesel to make "Union Jack Diesel", which was popularised by Prince Charles during the Queen's Silver Jubilee.
