Heads have rolled again at Sonatrach, where Kamel Eddine Chikhi was replaced as chairman and chief executive (PDG) on 5 February by vice-president for development and marketing Toufik Hakkar. PDG only since 18 November, Chikhi is a highly experienced Sonatrach exploration and production executive, well versed in pitching opportunities to IOCs, as he did in London recently. There have been rumours he was undermined by powerful rivals in the administration.
