Rosebank: UK's largest untapped oil field approved
Regulators have given the go-ahead to develop the UK's largest untapped oil and gas field in the North Sea. Rosebank, located 80 miles west of Shetland, is estimated to contain 500 million barrels of oil. Last month a cross-party group of 50 MPs and peers wrote to the energy secretary arguing it would be "deeply irresponsible" to back the scheme when the government should be driving down carbon emissions. Today's Martha Kearney speaks to Green Party MP Caroline Lucas, who opposes Rosebank, and Gilad Myerson, executive chairman of Ithaca Energy which has a 20 per cent stake in the project.
