SIR Mo Farah has revealed he has been hiding the truth about his life for decades — and even his name is not real.
The four-time Olympic champ, 39, bravely admitted making up key details about moving to the UK.
He previously claimed to have joined his dad, but he was killed in the Somalian civil war.
Sir Mo — real name Hussein Abdi Kahin — tells a TV documentary he was illegally smuggled here to work as a servant.
The running legend fears losing his UK citizenship.
“I’ve been keeping it for so long, it’s been difficult because you don’t want to face it. Often my kids ask questions — ‘Dad, how come this?’ And you’ve always got an answer for everything, but you haven’t got an answer for that.
“That’s the main reason in telling my story because I want to feel normal and not feel like you’re holding on to something.
“To be able to face it and talk about the facts, how it happened, why it happened, it’s tough. The truth is I’m not who you think I am. And now whatever the cost, I need to tell my real story.”
The revelations are laid bare in a bombshell new BBC1 documentary, The Real Mo Farah, which airs tomorrow night.
