Since I repatriated in 1997, as part of the relentless promotion of diversity in England, those with clipped southern or, occasionally, northern accents have been replaced by continuity announcers saying "bovver" or "nuffin," e.g.; and, it seems, the broader the foreign accent, the better - as we slide ever further down the greasy pole.

(I haven't heard "innit" from them yet, but did far too often when I lived in London.)
