Watch bizarre moment Iain Duncan Smith raps Eminem on Good Morning Britain

His palms are sweaty, knees weak, arms are heavy, Iain Duncan Smith raps on TV, get ready.

General election campaigns can take many weird twists and turns and, as the first line suggests, Eminem has been dragged in, remarkably by the former Conservative leader, Iain Duncan Smith.

IDS was appearing alongside Labour's Chukka Umunna to discuss the general election on Good Morning Britain when he burst into rap.

It came up when host Piers Morgan revealed that during the break, Duncan Smith had been rapping advice to Labour's Diane Abbott after a series of car crash interviews.

Morgan then prompted the former work and pensions secretary to repeat live on the air what he had said in the break.

He then ''rapped'' some of Lose Yourself, saying: "He opens his mouth, but the words won't come out, he's choking how, everybody's joking now, the clock's run out."

The presenter described it as "one of the most iconic cultural moments I have probably ever experienced on this sofa".

He said: "Iain Duncan Smith perhaps the last person you would expect to know this, was talking about a message for Diane Abbott and began reciting Eminem lyrics."
