Fleurpepper
A decent private school boarding fees are about 30.000 a year- but on top of that are many more other expenses, uniforms, trips, some acitivities, etc, etc.
The comment referred to school fees Fleurpepper and not extras. So £120,000 a year seems a lot for a few trips, unless they go to NZ every week, or wear Dior or Versace uniforms.
Joking aside, maybe the figure was plucked from mixing up fees per annum and then multiplying them by 3 terms. I'm sure the bursar would be delighted if that were the case.
But then the usual private school disapproval comments are to be expected when talking about various politicians.
