They are down to the final four in this year’s X Factor.

But whoever wins the contest, he or she will be helping Huddersfield families.

The X Factor winner’s single will be in aid of children’s charities Together for Short Lives and Shooting Star Chase, and through its links with the former the Forget Me Not Children’s Hospice will benefit from some of the proceeds.

There are four acts going into this weekend’s semi-finals: Lauren Murray, Louisa Johnson, Reggie ‘N’ Bollie and Che Chesterman.

The two acts who reach the final will each record a version of the song at Wembley Arena and the song will be available to download immediately after The X Factor winner is crowned on December 13.

Show supremo Simon Cowell said: “I have worked with these inspirational charities for many years and I’m delighted that The X Factor winner’s single sales will help families who are going through such unimaginably difficult times. In 2015, raising funds for hospice care is more important than ever. The money we raise will make a real difference.”

Who should win the X Factor?

Barbara Gelb, CEO of Together for Short Lives, said: “Together for Short Lives is so thrilled to be benefiting from The X Factor winner’s single again this year – it means so much to families caring for the UK’s 49,000 children and young people with life-shortening conditions.

“These children often have very complex and unpredictable conditions and need care around the clock. Working with The X Factor is transformational”.

Emma Kovaleski, corporate fundraiser at the Brackenhall-based Hospice, said: “ We are delighted that the X Factor Winner’s Single is going to be supporting Forget Me Not Children’s Hospice again. It will really help to raise awareness of the support we provide to local children with life shortening conditions and their families in West Yorkshire, best of luck to all of the final contestants.”
