Explorer Sir Ranulph Fiennes has failed in his attempt to summit Everest.
Everest: defeated Fiennes for second time
The 64-year-old was forced to turn back due to exhaustion while making the final assault on the peak. He had previously suffered a heart attack during an Everest attempt in 2005.
He arrived back at the South Col at 12.45am local time and is now heading back to base camp, where he is expected later this afternoon.
The expedition, led by Kenton Cool, was to raise money for Marie Curie Cancer Care.
The summit party set off from camp three at 7am yesterday, reaching camp four just after lunch. After resting, they set off for their summit attempt at 8.30pm.
There’s a blog and video of the expedition on the Everest Challenge website.
