Chancellor is in favour of North Sea project, but energy secretary has said she is leaning towards rejecting it

A cabinet split has emerged over whether to approve drilling at the Rosebank oilfield, with the chancellor, John Healey, in favour of the controversial North Sea project.

The energy secretary, Miatta Fahnbulleh, is ultimately in charge of the decision, and the Guardian reported last week that she was leaning towards rejecting it after granting permission for the smaller Jackdaw gasfield.
