The Metropolitan Police said a man in his 90s was interviewed under caution after agreeing to attend a police station near Farnham, Surrey.
He spent nearly two hours at the police station during which he answered questions. He was not arrested. Lord Bramall told the BBC he had no comment to make. The 91-year-old was questioned as part of Operation Midland.
