Memo row: What did David Mundell know and when did he know it?

Two weeks ago I explained why the Scotland Office should be wound up immediately.

I little thought that former Scottish Secretary Alistair Carmichael would provide such a spectacular example of why this must happen forthwith.

When you have a Government department which is responsible for nothing other than propaganda then it is perhaps unsurprising, if not excusable, when they get themselves ensnared in their very own propaganda web.

It seems impossible for Alistair Carmichael to survive as an MP from the wrath of his constituents having so narrowly won his seat on a false prospectus.

However, how about his former deputy and successor David “fluffy” Mundell? Are we expected to believe that he knew nothing whatsoever of the now notorious attempt to smear Nicola Sturgeon and the decision of his then boss to leak to the Tory house journal the Daily Telegraph?

In a department with so little to do he must have seen the infamous memo. And yet when it was mysteriously leaked he said nothing at all!

Mundell is about to be asked the age-old question: “What did you know and when did you know it?”
