Russian gas firm Novatek has delayed a roadshow of its planned share offering, potentially worth up to $1.5bn (€1.3bn), which was due to start in London today. It will instead start the roadshow on Friday in Moscow.

The deal is potentially the second-biggest initial public offering so far from a Russian group, behind the record-breaking $1.6bn IPO earlier this year from telecoms conglomerate AFK Sistema.
