Is the man in this video an Undercover Cop?

In the political world, things aren't always what they seem. 

The Conservative MP, Anna Soubry, has recently hit the headlines demanding that the police take action against pro-Brexit  far-right demonstrators who have been stalking her outside Parliament calling her a liar and a Nazi. Why the pro Remain MP should be labelled a Nazi, isn't quite clear, but it is believed that Soubry a former criminal barrister, is Jewish.

Soubry, the Member of Parliament for Broxtowe in Nottinghamshire, said she would not be silenced nor intimidated and that it was wrong that MPs should "have to accept this as part of the democratic process." She told the BBC News that the police needed to "do their Job" and would contact them about the matter.

Judging from a video that is being circulated on Youtube, it seems that the police may well be on the job, albeit undercover. The video shows a loud mouthed individual inciting a group of people to verbally abuse Soubry, who seems to be taking it all in her stride in spite of her claiming that she feels intimidated. 

Some people have suggested that the individual on the video is an undercover police officer. In part of the video, he can be seen to slip something into the pocket of a person accompanying Soubry, who is believed to be a personal assistant or security man.
