ETA: Tina, do you know whether a .doc version of this letter is available as the PDF maker used to create the file does not appear to faciliate copy and paste from the text, which makes the document difficult to quote extracts from if commenting on and the PDF may be too large to attach to a post (I've just tried and it would not upload)?
