When are the Brit Awards?

Who is presenting?

Ant and Dec have been replaced by X Factor presenter Dermot O'Leary and The Voice presenter Emma Willis.

Michael Buble was originally scheduled to host the awards show but had to pull out after his son became ill.

Willis said of taking on the role: "Every part of me sends so much love and all the best wishes in the world to Michael and his family at such a difficult time.:

O'Leary added: "Michael is such an effortless showman, so those patent shoes will not be easy to fill. But it's an honour to be asked to step in with Emma to host the Brits."
