Post Malone's Rockstar is narrowly denied a UK Number 1 by Sam Smith

Plus there are new entries and high climbers from Paloma Faith, Big Shaq, Mabel and Ed Sheeran.

Sam Smith’s Too Good At Goodbyes celebrates a third week at Number 1 after an incredibly close race on this week’s Official Singles Chart.

The track, which heads up Sam’s second studio album, keeps its place at the top after finishing just 693 downloads and streaming equivalent sales ahead of Post Malone’s Rockstar ft. 21 Savage, which climbs from 5 to 2. It’s the US rapper’s breakthrough hit in the UK, having previously reached a high of 28 with his last single Congratulations earlier this year.
