Anyone else watch Question Time last night?
One of the topics concerned the introduction of the Welfare Cap and during the discussion mention was made of a letter, leaked back in 2011, in which concerns were expressed within the government as to the cost effectiveness (or more to the point the lack of it) to the public purse of such a cap.
For some reason I had forgotten all about this letter and was very pleased to have been reminded of it.
Here's a link that will give you some more info.
