Who is the British Mark McMullen of Got Talent, and what happened to his brother?

This evening, Mark McMullen has absolutely congratulated the British judges of Got Talent with his interpretation of the movie Les Misérables, Bring Him Home.

He dedicated the song to his brother, Declan, who, he said, has a condition that he compares to "being buried alive."

Simon Cowell was in tears when Mark sang the song and a number of audience members also collapsed.

Simon told the hope, "Declan is lucky to have a brother like you. You bought a meaning to this song that I had never thought of before. "

He had four yes, so it will not be the last you'll see of the singer. Here is everything you need to know about him.

Mark is 23 years old and comes from Northern Ireland.

A few years ago, he was playing Bring Him at Ireland, Late, Late, Late Show, after a video of his song for Declan went viral, and his family was among the public who supported him.

His performance was so moving that Alfie Boe dedicated the song during his show in 2016 to their family.

What happened to Mark's brother?

Mark's brother, Declan – to whom he dedicated his song on BGT – has Locked-In Syndrome.

Addressing exclusively to Metro.co.uk, Mark said, "Unfortunately, at the age of 19, he suffered a cardiac arrest in his bedroom, as we were getting ready to go to school one morning. He just fell dead in the middle of the room, but obviously, at this point, he was getting up earlier than all of us in the house, so no one was awake to find out what was going on.

"We went to see him, while I was getting ready to go to school that morning, I noticed that he was in a strange position on his bed. He just did not look normal and I finally saw him and realized that at that moment he was dead, he was not breathing anymore. "

Mark and his father used CPR to revive Declan, but he suffered irreparable motor impairment and was paralyzed in all voluntary movements.

Although his dream is to sing, Mark became an architect so he could stay close to his family and help take care of Declan.

About why he joined BGT, he said, "I figured if Declan could do it, he would."

The British Talent Got continue on Saturday at 8 pm on ITV.
