@Pythagorus
Congratulations: You have driven TheNewbrown into threatening to make a "formal complaint." Respect.
@TheNewBrown while Pythagorous is considering, as no doubt she is, your kind offer to "name and shame" the Headteacher of the School her friend's child is at. (No reason why she would have any trouble with that, surely?) I have a modest suggestion for a way forward.
You see there is a Headteacher, who has, a number of times "propagated the lie" that setting up WPS is causing a hole of a bit over three million pounds in the repair budget for Islington Schools. He is in North Islington, so its not Pythag's friend's head.
His name is Barrie O'Shea, and he is Headtteacher at Duncombe School. I have no problem naming him on a public forum as he, for example wrote letters to the Islington Tribune and the Islington Gazette for the express purpose of "propagating this lie". He also attended a public meeting about WPS and spoke from the platform, and made the same point. Setting up WPS means a loss of funding to Islington Schools.
He is easy to contact, just go to the Duncombe School website. Google Duncombe School islington.
By all means contact him to tell him he is a liar. Go ahead with your "formal complaint"
But perhaps I should mention that he did what he did to point out the financial consequences for the children of Islington of WPS in his capacity as Chair of the Islington Schools' Forum, so he was acting as representative of all the other state funded schools in Islington. So in a way you are calling all the Heads in Islington liars.... So no half measures then.
