Its astonishing the amount of use of back-channels like WhatsApp groups by UK politicians. Its either gross stupidity or willful neglect of duty. Either should be enough to get them taken round behind the sheds and "re-educated".
In the commercial world we are constantly warned that this sort of behaviour is against policy but in the commercial world the risk of sanctions is real for both for the individual and the firm. Approved communications channels are there for one reason and one reason only, so that the contents can be archived for future reference. Going outside of that says either you don't get it or you don't want to get it.
IT specialists?
Remember the Scottish minister who took his Parliamentary iPad on holiday, the one with government and constituency business on it (or at least accessible via it)? Who then let his kids use it as a hotspot to watch streaming football matches and racked up a bill of tens of thousands in roaming charges? Who was extremely economical with the truth when the charges were highlighted by the media and was protected by the party elders for months until, even to them, his position became untenable?
Apart from all the political and personal failures to act with integrity, what sort of IT organisation sends out official devices that allow that sort of use?
