Lukas Graham hold on to number one for fourth consecutive week
Danish band Lukas Graham have seen off competition from Rihanna to hold the number one spot on the official singles chart for a fourth consecutive week.
Their international smash single 7 Years beat Rihanna's Work ft Drake, which comes in at number two.
Work has spent several weeks in the top five, and there was hope that it could reach the top spot after RnB singer Rihanna and Canadian rapper Drake's performance of the song at the Brit Awards.
On Monday it was just 8,000 combined sales behind 7 Days, according to figures from the Official Charts Company.
But Lukas Graham's single, a catchy song about growing up, sits atop the charts with combined sales of more than 106,000. This is the song's highest figure so far.
Work had been steadily rising up the charts and reached number two last week - having been at number three the week before, and number four before that - but failed to break out of second place.
However, the single was the most streamed track of the week, with more than 5.23 million listens.
Completing the top five is Mike Posner's I Took A Pill in Ibiza at number three, Zara Larsson's Lush Life at number four, and Jonas Blue and Dakota's Fast Car sliding two places to number five.
Manchester band The 1975 went straight in at number one on the official albums chart with their second album, I Like It When You Sleep.
Released last Friday, it follows their 2013 self-titled debut LP, and is also on track to become their first US number one on the Billboard 200.
The album has beaten Adele's 25, pushing her down the chart to number two.
At number three is Justin Bieber's Purpose, while retrospective album Best of Bowie is at number four and Coldplay's A Head Full Of Dreams is at number five.
The 1975 said they are finding their number one victory "surreal and weird".
Matthew Healy, Adam Hann, George Daniel and Ross MacDonald told OfficialCharts.com: "Thank you so much to everyone involved, we're very, very humbled by it.
"We're finding it a bit surreal and weird, we didn't expect it to go to number one, we're up against people like Adele, so we're really, really proud.
"And you get a trophy now, so we feel like we've actually won something too!"
Their second album achieved combined chart sales of 58,000.
This is 6,500 more than Adele's 25, which sits at number two on the album chart.
