The fact her kid acted terribly is one thing, can't really write her off for that.
The fact she used her position and influence and tried to hide it, less so.
The fact she put her child through private school because a state school was not up to the job, and now wants to push through laws that effectively try to kill the private school sector is damning to the highest order.
It's almost an equivalent of trying to improve the NHS by abolishing private health provision. Private healthcare takes a massive load off the NHS by removing the burden to care for a significant part of the population.
Like lot of Labour nonsense, it does not stack up, is hypocritical, and will almost certainly not improve the system they intend to target.
Madness. Total madness from the Red Comrades.
