He was elevated to The House Of Lords. I doubt that enhanced his humility.

I don't know anything about his humble origins, and I don't care about people's origins. He has a (rather weird, to my ear) northern accent, but being from the North doesn't make your origins 'humble'.

[Edit to add:] There's a word "chippy" that's used in England primarily to refer to Yorkshiremen. It suggests that Yorkshiremen all have a chip on their shoulder.

That's not my experience. Firstly, Northerners are much more accepted now than they were in my childhood; perhaps back then more Yorkshiremen were "chippy". Secondly, I've lived in Yorkshire, and I have never come across a sterotypical "chippy" Yorkshireman, except in TV dramas and comedies.

Chippy has nothing to do with people from Yorkshire. It refers to people who are overly defensive due to a sense of inferiority about their status or an imagined grievance. There are such people in Yorkshire, but there are such people everywhere.

I agree entirely. But the sterotype undoubtedly exists (or at least existed).
