Rita Ora and Ed Sheeran close in on Camila Cabello for this week’s Number 1 single

James Arthur, Craig David & Bastille, and Little Mix are hoping to bag new Top 40 entries this Friday.

It is now a three-horse race for the Official Singles Chart top spot as currently leader Camila Cabello takes on Rita Ora and Ed Sheeran for this week’s Number 1.

Camila’s Havana ft. Young Thug leads the Official Chart Update today, but just 200 combined chart sales (downloads and streams) separate Havana and Rita Ora’s Anywhere, at 2, meaning the chart’s leading ladies are closer than ever before.

Just behind them at Number 3 is Ed Sheeran with Perfect. The song, which he performed on The X Factor last weekend, debuted at Number 4 on the chart back in March following the release of Ed’s third album ÷, and could reach a new peak this week. A remix of the song with a mystery guest collaborator will be released this Friday.

Also hoping to secure a Top 10 position for the first time in his 20-plus year career, is MK, who rises six to Number 10 with 17.

One spot behind them at Number 23 are Craig David and Bastille with their new collaboration I Know You, which they performed on last week’s Sounds Like Friday Night.
