Bear Grylls led Everest trek in attempt to recover body of Spencer Matthews' brother

Bear Grylls has spoken out about his attempts to retrieve the body of a man who died in a mountaineering accident on Mount Everest.

As well as being close friends with James Matthews - Spencer and Michael's brother and Pippa Middleton's husband - Grylls holds a connection to Michael in how the 22-year-old overtook his record of being the youngest Brit to reach the top of Mount Everest.

However, it was only a year later when Michael managed to take the title from him on 13 May.

Grylls reflected: "It is the reality of high-altitude mountaineering, as people pay the ultimate price up there."

Finding Michael sees his younger brother, Spencer, retrace the climber's steps 23 years after his passing in a bid to try and discover his final resting place.

Spencer, who was 10 years old at the time of Michael's passing, took to Instagram to reflect on the upcoming documentary: "During recent years the question of whether or not Mike could be found and brought home to our family was often on my mind.

"I became uncomfortable with the thought of him being left up there, possibly in plain sight.

"[...] Over the last eighteen months or so we’ve been making a documentary film about this once in a lifetime journey to the highest point on earth.

"I am now proud to announce, together with @DisneyPlusUK that early next year we will bring you Finding Michael, a strong and powerful story of brotherly love.

"This has been the most meaningful and humbling experience of my own life and it is hoped the film will deliver my brave brother the decent legacy that he earned when so young. "
