I don't know who 'Big Jock' and how intimately he has known Archie, is so I don't know what level of trust to put in his assessment of the political commitment of someone I've known since he was 20 years old. He has in that time to my certain knowledge had several political thoughts, though not always ones I would agree with. Big Jock is so good at having strong opinions I think his given first name might be Gordon?
