An 80-year-old Japanese mountaineer has become the oldest person to reach the summit of Mount Everest.
Despite a history of heart problems, Yuichiro Miura, who climbed Everest when he was 70 and then again at 75, reached the peak early on Thursday morning.
But it is a record that could be short-lived, as Tom Bayly reports.
