Camila Cabello challenging Sam Smith for her first UK Number 1 single with Havana

There are projected climbs for Stefflon Don & French Montana, Craig David and Paloma Faith on today's Official Chart Update.

Is Camila Cabello on the verge of her very first UK na-na-Number 1?

The Cuban-born singer’s latest single Havana has climbed the Official Singles Chart over the last eight weeks, rising to Number 4 on last Friday's rundown. Havana currently sits at Number 2 on today's Official Chart Update, just 1,500 behind Sam Smith's Too Good at Goodbyes, which last Friday became his longest ever chart topper.

Havana became Camila's first Top 10 hit as a soloist three weeks ago, although she enjoyed a further two during her time as a member of Fifth Harmony. The band's biggest hit Work From Home, also peaked at Number 2.
