A few words on Israeli “diplomats” methods
I don’t think that Aljazeera would release this footage without the UK foreign department approval. Maybe someone inside the UK security services just took a page from the FSB book to make a point and to show to the Zionists that are being watched, recorded, and that they will be ousted.
We are also getting a glimpse of how the state of Israel operates. I recommend to watch a TV show Mossad 101 to get a basic understanding. This show explains that any Israeli can be a Mossad agent and to spy on the coworkers and friends, even to demand from people to kill someone, to hand them sensitive info, and so on.
