Chris Yelland: Back story to Mabuza resignation - and how to fix Eskom mess

When it comes to reporting in specialist areas, the best journalists are often those who have technical expertise in that sector. For instance, the late investigative journalist Barry Sergeant was a qualified advocate, skills which helped him negotiate the legal minefield that accompanies all serious challenges to the financially crooked. Similarly, mining journalism's doyens Lawrie Williams and late Adam Payne and David Gleason all spent years in hard hats and breathing in  the dust from underground. So when it comes to understanding the mess that is Eskom, our go-to guy is electrical engineer-turned-journalist Chris Yelland. In this fascinating interview on Rational Radio, Yelland applies his mind to the apparently shock resignation of the utility's chairman Jabu Mabuza - and issues which need addressing if the cynics who say SA is on the slide are to be proven wrong.
