Camila Cabello is still Havana good time on the charts as her latest single scores a fourth week at Number 1 on the Official Singles Chart. 

Havana ft. Young Thug comfortably extends its reign at the summit, finished 8,000 downloads and streaming equivalent sales ahead of its closest competitor, Rita Ora's Anywhere, which logs a second week at Number 2. 

Meanwhile, Silence by anonymous DJ and producer Marshmello and Khalid lifts two places to return to its Number 3 peak, and Ed Sheeran's Perfect lifts two places to Number 4 - matching its opening week debut back in March when Ed's ÷ album was released.
