On his newsblog, Nick Robinson links to the emails and letters sent between the NAO and HMRC.
As Robinson says:
The key thing we learn comes not from the detail but the tone of all the exchanges. They demonstrate little concern from either the NAO or HMRC about data protection. The NAO wants, it would appear, simply to reduce the size of the files it is sent. The HMRC is worried about the cost of filtering information in order to send the smaller files the NAO request. What about our privacy and our rights? No mention is made of them.
But arguably even more concerning is what’s to be seen on page 6 of the PDF – somebody at Benefits and Credits uses Comic Sans as their email font. Shocking.
