Christopher Chandler correction: In an article headlined “Who is hacking Brexit? And why we need our own Robert Mueller inquiry” published on 25 November 2017, our columnist, Liam Byrne MP, claimed that Mr Christopher Chandler had “helped to lead a boardroom coup to emplace Alexey Miller, Putin’s deputy from St Petersburg days, as head of Gazprom”. Mr Chandler strenuously denies any allegation that he helped to lead a boardroom coup to emplace Alexey Miller as head of GazProm. We did not have a basis to make this claim, which suggested that Mr Chandler had acted with an intention to place Miller, an associate of President Putin, as CEO of Gazprom. We also reported that Mr Chandler lives in Singapore. In fact, he does not (and has not) lived in Singapore. This correction has been published following an upheld ruling by the Independent Press Standards Organisation.
