Sky News Reporter John Craig dropped an on-air clanger this morning when he blurted out the 'F-word' - after being interrupted by Big Ben.

As Big Ben's bell rang, Criag turns toward Westminster and says: "Oh, fuckin' hell" before looking around angrily.

The mistake was on video, but it did not stop it from making it on air.  Back in the studio, an apologetic presenter tells viewers: "We do apologize for that, that was a much earlier recording and our apologies here from Sky News."
