Adele's record-breaking Hello debuts at number one in Britain

Adele is back at the top of the U.K. charts after Hello became the biggest-selling single of the past three years.

The soul star debuted her comeback song last week (23Oct15) and it has shot to number one with sales of 330,000 - making it the most popular track since The X Factor U.K. winner James Arthur's 2012 release, Impossible, which shifted 490,000 units.

The promo for Hello has also been breaking records online - the video, released on the same day, was viewed 27 million times within its first 24 hours, beating the record set by Taylor Swift's star-studded Bad Blood clip.

It also became the fastest video to reach certified status, or more than 100 million views, on entertainment platform Vevo.com, after just five days. Previous title holder Miley Cyrus took six days to achieve the feat with her raunchy Wrecking Ball video.

Meanwhile, back in the Official UK Top 40 Singles Chart, Justin Bieber is new at two with his latest track Sorry, just ahead of Drake's Hotline Bling at three.

5 Seconds of Summer have also been given reason to celebrate after scoring their first U.K. album chart-topper with Sounds Good Feels Good. They lead an all-new top five, with Bryan Adams debuting Get Up at two, and Andrea Bocelli new at three with Cinema.

Paul Heaton and Jacqui Abbott's Wisdom, Laughter and Lines and Daniel O'Donnell's The Hank Williams Songbook round out the new entries at four and five, respectively.
