Mercury nominee Plan B has been showing off his "ironic" outfit before the ceremony.

"I'm trying to be ironic. I wanted to come as a country gentleman, slash street kid. I've done my own tweed jeans. I'm going to go up there and have it up on the stage really," said the rapper.

Plan B, whose real name is Ben Drew, is nominated for his latest album, Ill Manors.

Drew revealed he wasn't expecting to be nominated for the prize, saying: "I was ready for it to have a small, cult fan base but not to do anything other than that."
