Schwarzenegger sends 'hidden' swear insult

Arnold Schwarzenegger has reportedly hidden a four-letter insult in a formal letter targeted at one of his political rivals.

The Republican governor of California seemingly coded the message in a letter about his rejection of Democrat Tom Ammiano's Assembly Bill 1176.

The first letter of each line in the second and third paragraphs of the veto spell out the phrase "F**k You".

Schwarzenegger's spokesman Aaron McLear said: "My goodness. What a coincidence. I suppose when you do so many vetoes, something like this is bound to happen."

Ammiano's spokesman Quintin Mecke responded: "Kudos to the governor for his creative use of coincidence.

"You certainly have to have a sense of humour in politics. Unfortunately, this humour came at the cost of the Port of San Francisco."
