Nominated artists Tinie Tempah and Professor Green will both be giving killer performances on the night; Green is up for Best Newcomer and Best Breakthrough Artist and Tinie Tempah will await to hear if he has won any of the staggering five awards he has been nominated for, which include Best Male, Best Song and Best Video. Scouting for Girls have also been nominated in the Best Radio Show or Podcast category, for the SFG TV podcast.

This year's nominees are a showcase of internationally acclaimed UK artists and with 21 categories on the cards, competition is fiercer than ever, with the likes of Cheryl Cole and Alexandra Burke not only fighting it out for Best Female Artist, they are also up against each other for Best Song.

Plan B, Chipmunk and Taio Cruz have all been nominated in both the Best Song and Best Male Artist category, where Robbie Williams and Dizzee Rascal have also been put forward. New celeb couple Rochelle Wiseman (The Saturdays) and Marvin Humes (JLS) will battle against each other to win Best Group, whilst a host of new talent including Example and Mumford & Sons will strive to be named Best Newcomer.

In the categories decided by the official judges, Damon Albarn and Jamie Hewlett's Gorillaz pick up multiple nominations, alongside Australian rock/drum n bass band Pendulum and BT DMA regulars, Muse. Meanwhile the BBC wins nominations for its Glastonbury 2010 coverage and its 2009 Ukulele Prom, as well as nods for its podcasts and shows by 6Music DJs Adam & Joe, and Radio 2's Jamie Cullum. Among the newcomers heralded by the judges, Marina & The Diamonds will fight it out against The XX, deadmau5 and The Temper Trap.

This year sees the introduction of some new categories for 2010 including Best Place to Hear, Discover and Buy Music, Best Event and Best Music App to reflect the increased audience engagement and rapid developments in technology that the music industry has seen in recent years enabling music fans to access their favourite music when and where they want.
