Meghan's second week at number one
Meghan Trainor has secured a second week at number one in the singles chart with her debut release All About That Bass.
She sold another 100,000 copies of the track after it was one of the fastest sellers of the year so far last week.
Jessie J, Ariana Grande and Nicki Minaj's former chart-topper Bang Bang held on to second spot.
Minaj's booty-shaking Anaconda was the highest new entry at number three. It is the latest single from Minaj's forthcoming album The Pink Print - due out later this year - and samples Sir Mix-a-Lot's Baby Got Back.
Taylor Swift's Shake It Off fell one place to number four, while US R&B star Jeremih's track Don't Tell 'Em featuring YG entered the charts in fifth place. It is his biggest UK hit to date after 2009's Birthday Sex peaked at 15, according to the Official Charts Company.
George Ezra is spending a second week at number one in the albums chart with his debut Wanted On Voyage.
The 21-year-old's folk-rock debut includes top 10 singles Budapest and Blame It On Me.
Hozier's self-titled album claimed the highest new entry at number five. The release by the 24-year-old Irish musician - real name Andrew Hozier-Byrne - includes hit single Take Me To Church.
Ed Sheeran's X climbed a place to number two, while Sam Smith spends a 20th week in the top 10 with In The Lonely Hour in third spot.
Barbra Streisand's Partners is at four.
