A bit of a CSB, but I was talking to two civil servants recently. One works for the FCO and the other in DIT, and both are working on Brexit. Both voted remain and are manager-level. Both also think that to not leave would be anti-democratic. Interestingly they both seemed a little frightened by the possibility of enraged gammons storming the streets of Westminster if a last minute revocation comes about.
I wonder how representative their views are of their civil service colleagues? Presumably just shows that all the institutions are working to deliver it in some form and that the "sabotaged by the Westminster elite" line is bullshit.
(Also their jobs sound like hell at the moment, massive hours, constantly cancelled holidays and whatever happens will be hated by 75% of the public)
