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

Miatta Fahnbulleh is leaning towards rejecting the giant Rosebank oilfield, the Guardian understands, in what would be a blow for the North Sea energy industry and a major victory for climate campaigners.

Officials say the energy secretary is minded to refuse approval for the field, which would be one of the biggest in the North Sea. Fahnbulleh approved the smaller Jackdaw gasfield on Wednesday, prompting protests from some in the green movement.
