Sam Smith’s Writing’s On The Wall is on course to become the first Bond theme song to top the charts on Friday.

The Spectre song has double the combined sales of its closest competitor, Justin Bieber’s What Do You Mean?

None of the previous 23 Bond themes have ever reached the top spot in the UK, although Adele’s Skyfall and Duran Duran’s A View To A Kill have come closest, peaking at number two.

The top five is completed by R City and Adam Levine’s Locked Away, with Sigala’s former number one Easy Love in fourth place and The Weeknd’s Can’t Feel My Face in fifth.
