I really don't care how an MP speaks - it's what they do that matters to me. You would think in this day and age this sort of snobbery would have died out, but it hasn't.
I do care about how someone uses grammar in their first language; she has claimed it is a dialect, which it is not, it is laziness and a lack of attention to detail, which is the flaw which ultimately was responsible for her downfall.
She has been given opportunities way beyond the reach of most MPs and wasted them, mainly because she was promoted beyond her capabilities. Her conduct was inappropriate for high office, and the 'oh she only made a mistake 'does not ring true; she had access to the highest legal advice possible, and the money to afford it, which many people do not.
The best thing she could do now would be to register at Ruskin College as John Prescott did, and study politics, if she thinks she still has a future there.
