I agree with her in principle. However, it's important not to confuse sloppy speech with the local accents and colloquialisms that enrich our language – often throwbacks to Old or Middle English. Thankfully, we've more or less got rid (except, of course, in The Archers) of the terrible Beebeecee accents that used to be so common on the airwaves.

My own particular bugbears are the influx of Americanisms (it's 'zed', not bloody 'zee') and the sloppy, slurry speech of the public school Hooray Henries and Henrieattas who insist on droppin' their Gs and saying 'gunner' when they mean 'going to' and 'yah' instead of 'yes'.
