Louis Tomlinson and Steve Aoki's new single is still placed at No.1 on the UK iTunes chart, despite facing competition from the X Factor winner's single.

The One Direction's man's first solo effort was released at the weekend after the duo performed the song on the X Factor, just days after Tomlinson's mum died from leukaemia at the age of just 42.

At the time of writing the tune is still No.1 on the main iTunes chart in the UK, with X Factor winner Matt Terry close behind at No.2. His song 'When Christmas Comes Around' was written by Ed Sheeran.
