Very fishy that he hasn't communicated any problems until now, after the uproar on Twitter and here. It's more than 50 minutes after his last tweet. Did he just spend that time typing this up?
That letter is a lie, unless someone from MAZARS confirms it. It would have some meaning if done way back in the begining. It is just an attempt to save what he can from the reaction here and Twitter. Dont fall for his BS again.
