I remember him (from abroad) as a gentleman politician or as close to that as one can get.
I also fondly remember a story told me by an East Sussex farmer. “Farmer” Callaghan wanted to burn his field once the crop/s were harvested, so he did. Unfortunately he was standing in the middle of it at the time I don’t know if that’s actually true or apocryphal but it’s a lovely image.
RIP. There aren’t many left like him among this lot.
