Katy Perry’s comeback track Chained To The Rhythm set for highest new entry on the Official Singles Chart

Plus Anne-Marie and Sia are set to make new Top 40 entries this Friday.

Ed Sheeran’s record-breaking stint at Number 1 and 2 could be coming to an end on this week’s Official Singles Chart.

The singer-songwriter still leads the way on today’s update with Shape Of You, on course for a sixth week at the summit, but Castle On The Hill has slipped to 3, overtaken by Rag’n’Bone Man’s Human. The song has so far leaped 5 to 2 following the release of his debut album and a performance on The Graham Norton Show last Friday.
