Like Gromit, SKS is indeed going into hiding, although he won't be able to hide tomorrow.
Gromit has been incredibly critical of BJ not having a piece of cake, and very supporting of SKS's beer and curry social - the latter as recently as Friday; the spin he's employed would have made a Dervish dizzy.
I couldn't give a tinker's cuss about BJ not having a piece of cake or SKS and Raynor enjoying a beer and curry social, and I don't think either are resigning matters, but it is the rank hypocrisy that rankles. SKS was calling for BJ's resignation during the investigation, and therefore as SKS is now being investigated, he should do what he was demanding of Johnson and resign - anything else is the rank hypocrisy mentioned above.
SKS's position is untenable, and cannot be defended, and that's the sole reason he's done a disappearing act today, and that's also why Gromit has decided not to participate in this thread.
