Sir Mo Farah has bravely opened up about his heartbreaking past, revealing he was trafficked into the UK as a nine year old boy to work as a servant.
The Olympian runner was brought into the country illegally in the place of the real Mo Farah, who still lives in Somalia.
Mo isn't his real name - was actually born Hussein Abdi Kahin in Somaliland - and for most of his childhood he was forced to live with a couple and take care of their young children while his own family remained in Somalia.
