The achievement of Sir Ranulph Fiennes, who reached the summit of Everest at his third attempt, was achieved with the support of sponsors Brewin Dolphin.

At 65, Sir Ranulph is the oldest Briton to summit Everest, and the first explorer in history to beat the mountain having also crossed both ice caps.

Jamie Matheson, Executive Chairman of Brewin Dolphin, said: “We are absolutely thrilled by the news – this climb was truly courageous.  Sir Ranulph made a speech at one of our client events last year and we were all so inspired that we wanted to do everything we could to help him make this record attempt.”

Sir Ranulph said: “I have summated Everest for Marie Curie Cancer Care which has long been a personal goal. Thanks to my sponsor Brewin Dolphin for making this possible. I urge everyone who followed my attempt last year to give generously to Marie Curie so that we can achieve our £3 million target to support its pioneering work in end of life care.”

Sir Ranulph first attempted Everest in 2005 but had a heart attack at 8,500 metres on the North Tibetan side. Last year, after reaching an altitude of 8,400 metres, he turned back due to exhaustion.
