Mika has held on to the singles chart top spot for the third week running with his track Grace Kelly.
He saw off a challenge from Fall Out Boy's This Ain't A Scene It's An Arms Race, which moved up four places from six to two.
Just Jack's Starz In Their Eyes was down one to number three.
This week's highest climber was The Prayer by Bloc Party, which jumped up nine places to number four. Exceeder by Mason made up the top five.
Over in the album chart, American singer Norah Jones raced straight to number one, with last week's chart-topper - The View's Hats Off To The Buskers - slipping to three.
Norah's Not Too Late became the 800th album to top the album chart since it started in 1956.
