Exxon, Repsol, shale gas

In this week’s podcast: Exxon’s deal with Rosneft puts an end to BP hopes for drilling in the Arctic; Spain’s largest oil producer Repsol is kept in check by two large shareholders; and shale gas – is it a low-carbon solution for the UK?

Presented by Sylvia Pfeifer with Vincent Boland and David Blair.
