Upon taking to the stage, Mark explained: ‘Bring Him Home is a very, very personal song for me and my family. ‘Nearly six years ago, my older brother took sick from a brain injury.

WHAT IS LOCKED-IN SYNDROME?
Locked-in syndrome is a rare brain disorder that causes complete paralysis of all voluntary muscles except the ones that control eye movements.
Sufferers are conscious but cannot speak or move. Their cognitive function is usually affected.
Locked-in syndrome is caused by damage to the brainstem that contains nerves that transmit information to other parts of the body.
Such damage usually occurs due to a lack of blood flow or bleeding following trauma.
Patients are unable to chew, swallow, speak or move, aside from their eyes, however, they can see and hear.
Most sufferers are bedridden and dependent on their carers.
Treatment focuses on relieving the underlying disorder, such as bleeding, if possible.
Patients may need tubes to help them breathe.
Small tubes are also inserted in their stomachs for eating and drinking.
Sufferers can be taught to communicate via their eyes.

But it was Simon’s words that proved the most poignant, as he said: ‘He’s lucky to have a brother like you
‘You brought meaning to that song, you managed to combine a real tenderness and then went into the strengths and I wouldn’t be surprised if off the back of this if you start getting calls from West End producers, I really like you.’
Many viewers were also left in tears by the emotional audition, and took to Twitter in droves to brand Mark a star in the making.
