U2 has scored strong early sales for its new set "No Line On The Horizon" (Mercury/Universal), which is almost certain to get the Irish rock band its tenth No. 1 album in the U.K. according to the Official Charts Co.

The OCC says that, based on sales figures on Monday and Tuesday, the album is selling four times the quantity of its nearest rival, "Invaders Must Die" (Take Me To The Hospital/Cooking Vinyl) by dance act the Prodigy.

Only Elvis Presley and the Beatles can claim more number one albums in the U.K., according to the OCC, which is suggesting U2 is likely to have the fastest-selling album of the year so far. The other acts with 10 U.K. No. 1 albums are the Rolling Stones and Madonna.

Billboard.biz understands that "No Line On The Horizon" sold 64,698 copies in the U.K. on Monday (March 2). The album has been released in a number of different formats.

Rudy Osorio, HMV head of music, said in a statement: "'No Line On The Horizon' is doing really well for us, and is certainly in line with the positive expectations that we have for its first week sales. The album should now have a strong base to build extensive sales across the whole year.

"As a specialist we're also seeing a lot of interest in the various formats such as the deluxe digipack and the box set, while hmv.com is enjoying some pretty decent download business."

U2 has also worked with HMV on its 'my inspiration' campaign, in which each of the members appear in print adverts nominating the artist lyrics that inspired them.

"We have been working hard with Mercury to maximise interest in this release, and we were thrilled when all four band members decided to take part in HMV's 'my inspiration' campaign by offering their individual lyric selections that have inspired them," said Osorio.
