Andy Murray's brother-in-law has become the youngest person to reach the South Pole solo.
Scott Sears, the brother of Murray's wife Kim Sears and a lieutenant in the First Battalion Royal Gurkha Rifles, pulled a sled and supplies for 38 days through 150mph winds in temperatures of -50c.

He completed the 702-mile trek at the South Pole on Christmas Day, 12 days earlier than planned.
Lt Sears carried out the trek for charity.
Antarctic Ghurka wrote on its Facebook page that the trek was "an effort to raise £25,000 for the Gurkha Welfare Trust".
It added: "The 1100km journey from Hercules Inlet to the South Pole is the equivalent of walking from London to the Czech Republic...it's just a bit colder...and windier...and there are crevasses to fall into...and you have to drag all your food and shelter with you...but otherwise it's basically the same."
The BBC reports that the first part of the journey from Hercules Inlet, where sea ice meets land in Antarctica, is considered the most dangerous part, as the ground is riddled with crevasses.
Lt sears was not roped to a teammate who could help stop him from falling, and used skis to cross the ice.
The 6ft 5in soldier pulled a sledge containing all of his food, fuel and equipment that, at more than 100kg (220lb), was heavier than him.
He said at points he hit a wall, and on Christmas Eve felt like he couldn't take another step, but persevered.
Speaking to the Telegraph, he said: "It's been an amazing 5 weeks, very tough at times but it all feels worth it now.
"I've been alone in a tent for nearly six weeks so it's all a bit overwhelming
"I can't wait to have a shower and get some food in me. I've been dreaming about it since day 3!".
He admitted that his mum had not initially been keen on the idea, but was very supportive.
He said: "She is eternally suffering because of me, I thought I managed to annoy her the most I possibly could when I joined the infantry and then I chuck this on her as well.
"I don't think she's slept for 38 days and she is as tired as I am."
Andy's mum Judy congratulated Sears on Twitter.
