Weed, Invader, or Neglected Squirrel Food?

A Horse Chestnut growing in the leaf litter and up against the wall. Perhaps the conker was discarded by a human.  Whatever the reason, this tree is going to struggle to prosper.

My extra was taken tonight, just before 10 pm when this polling station was about to close.  Fifteen hours of voting, but also more than 15 hours of work for election staff, and an equally long day for some political campaigners. Democracy eh!
