Katy Perry has scored a TransAtlantic double after taking her new single Roar to the top of the British charts just days after she reached number one in America.
Perry has ended Ellie Goulding's three-week reign atop the countdown with her fourth number one.
Goulding's Burn slips a spot to two, just ahead of Avicii's Wake Me Up at three and Klangkarussell's Sonnentanz (Sun Don't Shine) at four.
Meanwhile, in the albums chart, the self-titled debut album from The 1975 enters at number one, and Nine Inch Nails' new release Hesitation Marks enters at two. Acclaimed duo Rizzle Kicks debut Roaring 20s at three.
Also new to the top 10: Ariana Grande's Yours Truly at seven and Babyshambles' Sequel Prequel at 10.
