Just so that everyone knows where this number comes from.
Richard Murphy was hired by the union which junior level HMRC workers belong to. In order to produce a report which justified the reversal of the cuts in the number of HMRC employees which Gordon Brown had ordained following the merger of the Inland Revenue and Customs.
This was the point and purpose of the report and of the hiring of Murphy. It was nothing at all to do with how to make the economy function better, nor how to close a deficit or anything at all like that.
Purely, find a way that we can argue that the merged organisation should not have fewer staff.
Thus all of the recommendations about how to close the tax gap contain “hire more people at HMRC”.
And that really is it.
