I'd say the big shareholders were happy enough with Goyder, Hey and Brenner going that Sampson could stay. No idea why, he's brought exactly zero to the board and company.
I read that re-appointment as yet more evidence of 'no change' from the very top. As anyone who has worked at QF in the last 20 years would know - the LAST thing Qf needs is more propaganda and spin. I'd have been thrilled to see a Steve Purvinas type rather than someone with absolutely no operational or front line experience whatsoever.
