British man Aiden Aslin joined the Ukrainian marines in 2018, but following the Russian invasion in February 2022, he was called up to the frontline in Mariupol.

After two months of resistance at the city's steelworks, Aiden and his battalion ran out of supplies. Aiden was part of the mass surrender of over 1,000 Ukrainian troops.

Singled out for his British passport, Aiden was brutally interrogated, turned into a propaganda tool, tried by a kangaroo court and then sentenced to death.

Aiden was held in Russian captivity for six months, before being released last year in a prisoner of war exchange negotiated by the Saudi authorities.

On the Sky News Daily, Niall Paterson sits down with Aiden Aslin to hear his story.
