Spencer also shares son Theo, four, and daughter Gigi, two, with wife Vogue Williams.

Next to the snap Spencer penned: 'Mike and Otto at similar ages…

'Apart from Otto's larger mouth (which he obviously got from Vogue) I'd say they're pretty similar!

'I already feel like our kids have some of his kind and adventurous nature.'

Michael's body has never been recovered and his family have never been able to fully understand what happened to him. 

Finding Michael, which is is now streaming on Disney+, shows Spencer's emotional quest to find his late brother's body with adventurer Bear Grylls and record-breaking mountaineer Nirmal 'Nims' Purja. 

During the film, Spencer, who was just 10 years old when his brother died, undertook a 'gut-wrenching' mission to climb Everest to find his brother's body, retracing the 'exact steps' his sibling took when he died. 

Speaking on The One Show, Spencer said: 'When Michael went missing, by the time some people realised he was missing, it was too late. Nobody survives the night, really. A couple of cases maybe.'

Michael is said to have got in trouble after beginning to make his way down the south descent through the 'death zone' on May 13, 1999, after spending around 20 minutes at the summit.

He was also the brother of Pippa Middleton's husband, the racing driver turned hedge fund manager James Matthews, 47.

The experienced mountaineer, who had previously conquered Aconcagua, the Pyrenees and the Swiss Alps, was the 162nd person to die on Everest.

Spencer went on to detail how he made the 'difficult decision' to undertake the mission himself.

'In 2017, the family was sent a photo of a body on the mountain and they claimed that it could be Michael. In fact it did look like it could be, with similar summit suits. It's the first time really that I thought even a body recovery was possible.

'It continued to tick away in my head: "What if it is him?". I've certainly grown up with feelings that he's up there and died and was left there. Wouldn't it be nice if there was a body to mourn for my family?'

'We scrapped together any information we had. Some of the footage of Michael on the mountain I'd never seen before,' he said, becoming increasingly more emotional as the interview progressed.

'It was the first time I'd seen him on camera, because as a kid we didn't do home movies or anything.

'Retracing his steps and understanding his final days a bit better was quite cathartic for me...'

Finding Michael is now streaming on Disney+.
