This is the video of Sadiq Khan’s top aide Shueb Salar brandishing a rifle. He bragged about “shooting stuff with real guns, knives, crossbows and bow and arrows” and added the hashtags “I’m A Secret Hitman”, “Shout Me If You Want Me To Take Care Of Someone” and “I’ll Make It Look Like An Accident”. Unfortunately for Sadiq this is hitting the London news bulletins now and is going to be read by up to a million voters on the front page of the Standard tonight…
