Ritchie attempts to come back and insist that Oxfam weren’t tax avoiding but Amazon were. There’s a couple of fun points, for example, “Did they take the risk of their arrangements being challenged by HMRC when adopting this structure?”. Well, yes, Oxfam did. Because HMRC used to routinely deny those very arrangements. Which is why the use of them is quite modern.
But the really fun one is:
“Has what they did been subject to mainstream political criticism?”
That is, if Margaret Lady Hoxja accuses you of tax avoidance this is then to be used as proof that you are tax avoiding.
Or, as we might put it, tax avoidance is you paying less tax than Richard Murphy thinks you should be paying.
