The Guardian are certainly a left-leaning, frequently political paper, but that doesn’t mean every story is political, and IMO this one isn’t.
The rest are political ads.
Contrast the BBC's take: First American wins World Conker Championships[0], which focuses on the winner's family's pride, the "lovely little village" where the tournament was held, the American visitor triumphing over churlish natives heckling her, and concludes with a cozy panegyric embracing both tradition and the New World Order (of conkers):
> "Our overall champion, Kelci Banschbach, is our first American Queen Conker and David Jakins, previous finalist and long-standing committee member, very much deserves his King Conker title."
In typical fashion, the Establishment's champion declines to even hint at the underlying corruption.
Fox hunting, horse riding, polo and skiing... yes. Conkers, No.
I'm sure there are parts of the country where they're less common, but there's huge numbers of conkers falling off trees in big British cities (even if the majority will be in parks) as well as in the countryside. We played with them at my pre-teen city centre school for sure, and the trees are a common sight on roads and in gardens as well as public parks.
edit: the Woodland trust actually says "Though rarely found in woodland, it is a common sight in parks, gardens, streets and on village greens."
[1] Which kind of sucks for me personally because they cause me really terrible hayfever. I think I'm specifically alergic to their pollen maybe.
