According to the IAC voting figures for the ninth place vote off when Nadia left, Michael was ahead of Vicky, Kendra and Edwina. He made it clear though, how disappointed he was to not be leaving. Perhaps if he hadn't, he'd have been in the last five with Foggy, Jake, Mel and Tinchy.
I'd been voting for him but stopped because he obviously wanted to go. It turned out that he'd been losing a pound a day in weight. He looks over 6ft and came out weighing under ten stones. The newspapers made a thing of that, inferring that he might have to leave. When checked by a doctor, in camp, his blood pressure was described as " Olympian" but the negative publicity was already out there. Was voted hardest working campmate by the way so he hadn't been sitting around conserving energy as some, campmates had. Perhaps all that influenced other people as well who'd been voting for him - possibly.
Trying to remember how Christopher Biggins won. He, must have been very popular but I can't imagine or remember why so voting behaviour is often a mystery - unless a soap star or boyband member wins.
