I think Cockney rhyming slang is wonderful and adds to the gaiety of the nation and we would be the poorer without it. A soft Welsh accent is wonderful (there's lovely), as is the Aberdonian lilt and I love the Geordie way of speaking. And I adore the Yorkshire accent and the way the people only use half the number of words others would use, ie It isn't in the tin - Yorkshire version, T'intintin!
So I shall vote No.
