Number One milestone for Danish group Lukas Graham
Lukas Graham's international hit single 7 Years has become the longest-reigning number one from a Danish act in UK chart history.
With a fifth consecutive week at the top of the official singles chart, the band have broken the record held by Whigfield's 1994 hit Saturday Night and 1997's Barbie Girl by Aqua.
The foursome, led by Copenhagen-born frontman Lukas Graham, shot to success with their catchy song about growing up.
7 Years finished more than 20,000 combined chart sales ahead of its nearest rival, Mike Posner's I Took A Pill In Ibiza - and was the week's most streamed track at 4.52 million listens, according to figures from the Official Charts Company.
The track has also become the longest-reigning chart topper since Mark Ronson and Bruno Mars's dance hit Uptown Funk clocked up six straight weeks at number one from December 2014 to January 2015.
Justin Bieber achieved five weeks at number one over November and December 2015, but the victory was split between two different tracks - Sorry and Love Yourself.
Adele has also bagged herself another number one, as 25 makes a triumphant return to the top spot of the official albums chart for a 10th non-consecutive week.
The Hello singer's chart success comes as she performs to packed arenas during her tour, which will next bring her to London's O2 Arena for a week-long residency.
Adele's third album enjoyed a more than comfortable lead as she notched up over two and a half times the chart sales of her nearest rival this week.
Jess Glynne's I Cry When I Laugh is at number two, while Bieber's Purpose is at three.
Best Of Bowie, a hits retrospective, sits at number four and Coldplay's A Head Full Of Dreams is at number five.
In the singles chart, Rihanna and Drake's single Work has slid one place to number three, while Zara Larsson's Lush Life is at number four.
Jonas Blue and Dakota's Fast Car completes the top five.
