London: Bernie Ecclestone says he is relieved to be back running Formula One but feels "a bit of an idiot" after settling his bribery trial in Germany on Tuesday.

The 83-year-old F1 supremo was back at his desk in London hours after walking out of the court in Munich, his case brought to a premature end after the British billionaire arranged to make a $100 million (75-million-euro) payment.
