Kate Perry h eads the nominations for MTV's European Music Awards as she competes for seven prizes, just ahead of Ariana Grande in the running for six.

Pharrell Williams, who has enjoyed huge success on the back of his chart-topping hit Happy, competes for five trophies along with Australian pop act 5 Seconds Of Summer.

The winners will be announced at a star-studded show to be staged at Glasgow's SSE Hydro Arena on November 9.
