Lady Gaga toppled from top spot
Lady Gaga was toppled from the number one spot in the singles chart by a new entry from Scouting For Girls.
The band's single This Ain't A Love Song took the top position, pushing Telephone, the flamboyant singer's single featuring Beyonce, into second place.
Her album The Fame also remained at number two in the UK chart, behind Boyzone's tribute album to Stephen Gately, called Brother, which clung on to the top spot.
Brother went straight in at number one on March 14, then dropped to number three, before returning last week to the top spot in the album chart.
The rise in sales followed the band's emotional television show Boyzone: A Tribute to Stephen Gately which was broadcast on ITV1 a fortnight ago.
Gately, 33, was found dead in an apartment on the Spanish holiday island of Majorca last October.
The band's single Gave It All Away, which features the last vocals Gately recorded before he died, fell 12 places to 22 in today's chart.
There were two other new entries in the top 40 singles chart, with Plan B's She Said appearing at number three and History Makers by Delirious at number four, The Official UK Charts Company said.
Cheryl Cole's single Parachute fell five places to number 10, while her album 3 Words rose one place to number 12.
There were six new entries in the top 40 albums, with Craig David's latest release Signed, Sealed, Delivered at number 13 and Madonna's Sticky & Sweet Tour album going in at number 17.
