Elsewhere in the top ten, Karmin climb from six to five with 'Brokenhearted', Underworld's Olympics track 'Caliban's Dream' lands at seven, and Rudimental's 'Feel The Love' slips from seven to complete the top ten.

Other new entries as a result of the Olympics Opening Ceremony include Arctic Monkeys' 'Come Together' at 19, and Emeli Sandé's 'Abide With Me' at 32.

On the album chart, Conor Maynard leads the tally with his debut effort Contrast, pushing Plan B's iLL Manors to two.

Delilah's From The Roots Up debuts at three, Mike Oldfield's Two Sides...The Very Best Of starts at six, and Rick Ross is a new entry at seven with God Forgives, I Don't.
