The senior management team outside of the board can ensure a smooth transition.
An interim Chairman / board can be appointed if required, and it may come to that, but ideally not.
MSP have no need for Kenwright for any period of time, and surely recognise what a toxic figure he is. They surely cannot want a new era for the club to begin with Kenwright in situ, with all the uncertainty and unease that would bring.
If he was there for a couple of days as a placeholder in the aftermath of MSP formally committing, then I don't think anyone would care ultimately, but every day he's still here causes concern that things are not changing and will not change. People can take no more of his malign influence and hostage-taking.
I hope the delays are from doing what needs to be done to remove Kenwright, whilst work on finalising with MSP and the new board continues in parallel. Then we can have a fresh start of sorts at least.
