Exclusive: Officials say Miatta Fahnbulleh minded not to give approval in victory for climate campaigners

Miatta Fahnbulleh is minded to reject the giant Rosebank oilfield, sources have told the Guardian, in what would be a blow for the North Sea energy industry and a major victory for climate campaigners.

After approving the smaller Jackdaw gasfield on Wednesday, officials say the energy secretary is leaning towards refusing approval for what would be one of the biggest oilfields in the North Sea.
