Hackney is a twin-town with Haifa in Israel - so too is Portsmouth.
Portsmouth's popular nickname (especially re its football club) "Pompey": there are a number of theories put forward for the origin thereof. My favourite one, involves a character whom I have mentioned before in this game: the earnest and pious, and pleasingly eccentric, lady Agnes Weston (I'd thought, prior to Googling just now, that her name was Agatha) -- dates 1840 to 1918. Agnes W. had a big concern for seafarers, and ran various programmes to instititute helpful facilities for them; hoping also thus, to lead them into the paths of righteousness. Although the seagoing guys mostly reckoned that she was on a hiding to nothing as regards this last; they developed a considerable affection for her, calling her (not to her face) "Aggie". Per this account, the "Pompey" nickname came from a lecture to the tars, conducted by A.W. in Portsmouth, on ancient Roman history; including the sad fate of the figure therein, Pompey. In the course of the talk, someone became quite emotional and cried out, "poor old Pompey !" -- which for some reason, really took the seamen's fancy, and "it led on from there".
The lady's nautical "clients" took to -- per a bit of bad punning -- calling
Weston-Super-Mare (Somerset), "Aggie On Horseback".
