Mark Ronson is on course to spend a fifth week at the top of the UK singles chart.

The Official Charts Company confirmed in their midweek update today (January 14) that his smash hit 'Uptown Funk' is still No.1.

It is currently selling 25,000 units more than this week's No.2 - Philip George's 'Wish You Were Mine' - which means it should spend a fifth week at No.1.

This will make Ronson the longest running No.1 in the UK since Robin Thicke's 'Blurred Lines', which achieved five non-consecutive weeks at No.1 in 2013.

At No.3 on the midweek update is Hozier's 'Take Me To Church', whilst Olly Murs' 'Up' follows at No.4.

Rounding off the top five today is Ed Sheeran's 'Thinking Out Loud'.

Sia meanwhile rests at No.14 with her new single 'Elastic Heart'.
