Sir, – We know that the main ingredient for a nerve agent is organophosphorus, a chemical invented by a German chemist in 1932, and this has been debated by the learned in most universities in the past month over the accusation made by the UK government against Russia.

Now that the government has the knowledge all about nerve agents why don’t they come clean and admit that when sheep dipping was compulsory, a lot of farmers and helpers suffered as a result from the exposure to this nerve agent, yet the government ignored their pleas?

It is a pity that the sheep dip chemicals weren’t made in Russia, then those thus contaminated would have been given compensation and a new life in the USA.
