Mea culpa! After discussing this with my wife it turns out that it was Michael Portillo on our flight, not Archer.
Portillo was much more amiable that I’d presumed. I cannot comment on Archer.
Many politians are very amiable when you speak to them personally, which is, I guess, one the most important elements of the job spec, although some, I hear, come across as really nasty pieces of work. Archer? Never met him, but he clearly had a level of charisma that is well beyond that of a normal person. How else could he have bagged the job, wife and mistresses that were clearly well beyond his upbringing?
But Michael Portillo, on the other hand, seems like a genuinely nice guy, despite his political reputation. His Railway Journeys TV series shows him happy and willing to put those he meets front and central on the camera and in the narative, rather than as a stooge for his own personality. On a cycling note, his meeting with members of a Clarion Club as part of this series, a cycling organisation routed in Socialist ideology, showed mutual respect despite polar oppposite political views, with the conflicts of opinion taken in good humour.
