Sheffield's Arctic Monkeys look likely to land their sixth number one album as their new record is currently outselling the rest of the top 20 combined.
The rock band's new album Tranquility Base Hotel And Casino has accumulated 66,000 combined chart sales since it was released on Friday, 67 per cent of which is comprised of physical copies on CD and vinyl, the Official Charts Company said.
The Alex Turner-fronted group's previous five albums - Whatever People Say I Am, That's What I'm Not (2006), Favourite Worst Nightmare (2007), Humbug (2009), Suck It And See (2011), and AM (2013) - have all hit the top spot.
The release of Tranquility Base Hotel And Casino marked the hotly anticipated return of Arctic Monkeys, who had been on hiatus since 2014.

As well as the new record's sales triumph, three of their other albums are set to re-enter the top 40 - AM, Whatever People Say I Am, That's What I'm Not and Favourite Worst Nightmare.
A number of tracks from the album have made their way into the top 40 on the singles chart too, including Four Out Of Five at number 12 and Star Treatment at number 13.
Previous chart-topper The Greatest Showman soundtrack is down into second place at the halfway stage of the charts week, one ahead of a new entry from US singer Charlie Puth, whose album Voicenotes is on course to debut at number three.
