English has many dialects, of which, some are North American. British English is a peculiar idea. By definition it would include Doric, Shetlandic, Estuary, M.L.E., Geordie, R.P., Brummie, Scouse, Faroese (at a stretch), and several others. It is both difficult and reductive to generalise across this diversity. In previous centuries there have been (often cruel) attempts to use the education system to impose uniformity on regional and national linguistic identities. In some cases (notably Wales) these have fueled lingering political resentments.
