Louisa Johnson has recorded the lowest chart entry

Louisa Johnson has recorded the lowest chart entry for an X Factor winner's first single, making her debut in this week's UK singles chart at number nine.

Every other winner of the ITV talent search, bar two, has hit the top spot in their single's first week on sale.

Johnson's single Forever Young is at a comparative disadvantage, however, as only four days of the chart week count towards her song's chart position.

This follows the shift of the singles and album chart from Sunday to Friday.

Weekly chart positions are determined by sales from Friday through to midnight on Thursday, and Forever Young did not go on sale until Sunday night.

Only Steve Brookstein and Joe McElderry previously failed to claim the top spot with their winners' singles in their first week.

Both initially had to settle for a number two slot, in 2004 and 2009 respectively, though both tracks did subsequently climb to pole position.

Without a realistic challenge from this year's X Factor winner, Justin Bieber remains at number one for a third week with his track Love Yourself.

With his previous single Sorry holding fast at number two, the Canadian star is now the first artist to spend four weeks at numbers one and two consecutively.
