Lukas Graham are on course to spend a second week at No.1 in the UK.

The Danish band's track '7 Years' hit the top spot on Friday (February 12) and at the midweek stage it is still No.1.

The Official Charts Company says the tune is currently outselling Zayn Malik's 'Pillowtalk', which remains at No.2.

The midweek top five is unchanged from Friday's chart, with Jonas Blue's 'Fast Car' No.3, Rihanna's 'Work' No.4 and 'Stitches' by Shawn Mendes at No.5.

Sweden's Zara Larsson's 'Lush Life' rises seven places to No.9.

Rising UK indie group Viola Beach are in at No.39 after all four members and their manager were killed in a road accident in Stockholm at the weekend.

Their track 'Swings & Waterslides has broken into the top 40, with proceeds of the single going to families of the band and manager.
