Dear Secretary of State
My friend, who is in farming at the moment, recently received a cheque from the Rural Payments Agency for £3,000 for not rearing pigs. I would now like to join the 'not rearing pigs' business.
In your opinion, what is the best kind of farm not to rear pigs on, and which is the best breed of pig not to rear?
I would prefer not to rear bacon pigs, but if this not the type you want not to be rearing, I will just as gladly not rear porkers. Are there any advantages in not rearing rare breeds such as saddlebacks or Gloucester Old Spots, or are there too many people already not rearing these?
My friend is very satisfied with this business. He has been rearing pigs for forty years or so, and the best he ever made on them was £1,422 in 1968. That is until this year, when he received a government cheque for not rearing any.
Yours faithfully (etc)
