The Post Office has disowned and repudiated a letter that had been issued to subpostmasters, threatening them with the loss of their compensation for the closure of their branch if they failed to toe the company line when talking to customers about the coming closures. The letter threatened visits by "mystery shoppers" to the subpostoffices to check up on compliance. The Post Office has now apologized for the letter and assures subpostmasters that the measures threatened in it would not be taken.
