Biffy Clyro have scored their first number one album with Opposites, the Official Charts Company said.
The band reached number two and number three respectively with their two previous studio albums, Puzzle in 2007 and Only Revolutions in 2009.
"Opposites feels like the best record we've ever made and to have it sitting atop the Official Albums Chart is a huge honour," the band told OfficialCharts.com. "Thank you so much to all our fans."
Opposites has sold 71,500 copies this week, which is not only the biggest opening week tally for an album this year so far, but also a personal best for Biffy, eclipsing the first week sales of their previous top 10 albums.
Opposites relegates The Motion Picture Cast Recording of Les Miserables to number two on the Official Albums Chart, while 35 years after its release, Rumours is back in the top three as the Fleetwood Mac album finishes the week at number three.
Meanwhile, Dutch dance duo Bingo Players remained at number one for a second week in the singles chart with a track that failed to make the top 40 in their native country
The single Get Up (Rattle), featuring Far East Movement, knocked pop princess Britney Spears and Will.i.am with Scream & Shout off the top spot last week, and the Dutch pair said the continuing success "means the world".
"We have always watched the UK charts as a great indicator of what's to come next and really admired and looked up to great British dance artists and producers like The Prodigy and The KLF. Now to be among those ranks means the world to us," they said.
Macklemore & Ryan Lewis featuring Wanz rocketed up the chart as Thrift Shop, their ode to second-hand garments, jumped 22 places to number two. Thrift Shop has already topped the charts in Australia, New Zealand and the US's Billboard Hot 100.
