Beastrabban is slightly inaccurate in his account of events on my blog, Vox Political. I am told (by the DWP) that readers of my blog just copied and pasted my FoI request and then sent it as their own – but I have yet to see the proof of that.
The point I would make is that readers need to take the spirit of the letter, together with the factual evidence it contains, and write their own version, based around it. There should be no implication that it is a lookalike or identical piece.
