I'm not so sure Cessnafly. When sponsorship is agreed the sponsor will want certain assurances that certain things will be done and others will not. They certainly do not want to their name or products to be associated with any controversy, unless that is their aim. Their problems come when things do not go according to plan and their organisation starts to become associated with scandal and their professional ethics are called into question. When they are, do they quietly slide into the back of the crowd or do they loudly march out of the room shouting that they have been had? I'll suggest that Artemis want a quiet exit, will say that this has been a worthwhile programme, cross their fingers that their name will no longer be mentioned and cross her name off their Cristmas card list.
Apparently Alistair Campbell, some would say the real deputy PM, would give a controversy two weeks to run. If it went over that, he would chop the person involved - whether they were innocent or guilty. On their termination, he would release that person X has done a marvellous job and the time was right for them to look forward to seek to challenges elsewhere. Maybe in spending more time at home, or buying a MaccyD franchise, or whatever. This is probably Artemis's face-saving way of giving TC-T the chop.
It's just a shame we didn't see the look on her face when this good news arrived.
