A Fox News anchor has been caught off guard during a live report when the camera accidentally cut to him fidgeting and staring awkwardly down the lens.

Michigan's Fox 17 Morning News reporter Tamra Johnson was speaking to the camera when it jerkily cut away from her to the news desk.

Anchors Mike Avery and Sarah Brodhead initially look bewildered as they realise the camera is trained on them.

Avery gives his co-host an uneasy look before giving the audience a wave as the camera remains on them for about 20 seconds.
