Inner London is different from the rest of the country because it’s the only part that looks like Western Europe. Starting in Putney, the UK is a giant periphery, with kilometres of houses and nothing to do apart from getting the train to Inner London. There’s more stuff to do in my grandmother’s village than in the entirety of West London after Hammersmith. At least, in that 1200 people village, there are 2 fully operational churches (one 1000 year old), a football field, 2-3 restaurants/cafes and a castle. Outside of inner London the density of foreigners drops dramatically, which in Brexit England tends to be a problem.
Why would anybody in their right mind go to Nowhereshire instead of going, say, to Berlin or Milan or even Perugia?
