Rishi Sunak’s rollout of his new energy plan on Monday degenerated into a heated exchange on BBC Radio Scotland as the prime minister angrily defended his plans for new North Sea drilling and his frequent use of private aviation.Before jetting up to Aberdeenshire, Mr Sunak was grilled by presenter Martin Geissler who complained he had been given only five minutes by No10 for the interview.The prime minister said that was a “strange way” to begin, and the interview ended with him accusing Mr Geissler of wanting to ban foreign holidays, after the presenter asked why he was taking a private jet to tout a “green” plan.
