Jeremy Corbyn's comms chief just broke the number one rule for spin-doctors

The leader of the Britain's Labour party Jeremy Corbyn made a brave choice when he appointed Seumas Milne, the left-wing newspaper Guardian columnist, as his new Director of Strategic Communications.

The firebrand journalist has no previous experience in communications, let alone running the media operation of a major political party.

And today, his inexperience showed when he made a big mistake while Corbyn was being interviewed on Sky News - he video-bombed him.

The number one rule of being a spin doctor is to always be behind the camera.

Here he is appearing over Jeremy Corbyn's shoulder.

Then casually walking behind his leader.

He tries to hide his face as he passes the camera.

You can watch it happen below:

Communications Directors try to never appear in the news at all and stay out of the way when the cameras are rolling because they don't want to become the story. It looks like Seumas is going to have to learn the hard way.
