On tomorrow night’s Britain’s Got Talent, hoping not to hear any buzzers is 62 year old retired swimming pool manager Mike Henderson. As Mike explains to Ant and Dec, his very dangerous act, “I handstand on knives and I’ve got another knife inverted, pointing upwards towards the throat, if the buzzers goes at the wrong time I really could hurt myself”.

Mike looks wobbly but gets up in a handstand balanced on the knives, just as it looks like his arms are wobbling too much and he may fall Piers hits his buzzer and Mike falls direct into the path of the knife, Kelly screams, Amanda runs away from the desk and Simon recoils in shock, has Piers’ mistimed buzz resulted in the first injury on stage, or is Mike a pro and taking it all in his stride?
