Ministers are poised to approve a controversial new gasfield in the North Sea this month, according to government sources, and are considering approving a major oilfield later this year.

Miatta Fahnbulleh, the energy secretary, will give her recommendation to approve the Jackdaw field off the coast of Aberdeen as soon as next week, according to people close to the decision, and the formal approval could follow a week after.

Meanwhile, officials are looking for ways to make sure any proceeds from the separate Rosebank project – if it is approved – go towards clean energy projects, as happens in Norway.
