King, from West Hampstead, north west London, initially pleaded not guilty to the charge when he appeared before magistrates last November. One of his tweets stated “I can hear the screeching of the nails as I sharpen them for your crucifixion” and another said: “I am planning the writing on your gravestone.”He went to the couple’s £10 million home several times.In a statement, Mrs Lampard, who is pregnant with her first child, told Isleworth Crown Court: “I do not go out alone anymore. I always go out with someone.” Christine Lampard, the television presenter, has revealed she is too terrified to go out alone after being hounded by a stalker for three years.She was once forced to hide in her bedroom and on another occasion was left cowering behind the sofa when he repeatedly turned up at her London mansion, having bombarded her with “dark and disturbing” tweets, emails and letters, a court heard.Christof King, 39, who believed it was “his destiny” to be with Mrs Lampard, the wife of former England footballer Frank Lampard, pleaded guilty yesterday (FRI) to one charge of stalking causing serious alarm or distress, having previously denied the allegation.But Mrs Lampard, 39, could be forced to face him in court on Monday because he denies sending certain tweets and knowing that his behaviour amounted to harassment.The judge, Robin Johnson, has scheduled a Newton hearing to determine the full extent of his campaign and may ask to hear directly from Mrs Lampard, who had been expected to give evidence from behind a screen at his trial.His findings will determine the severity of King’s sentence. He faces a maximum of five years imprisonment. Mrs Lampard revealed last year that King had booked himself into her hotel when she was away with her husband.She told ITV’s Loose Women: “There was a chap who had been trying to get in contact with me for a while.“He thought we were married in his mind.“He randomly turned up at the hotel we were staying in, which does freak you out because there’s a sense that he knows where you are.“Frank did go out and say, ‘Look, you’ve got to stop, this isn’t normal behaviour.” Frank Lampard described how King turned up at their front gate, forcing his wife and their housekeeper to hide in the bedroom because they were so frightened.“’It has both made us feel very vulnerable, she became flustered and very nervous and concerned for her safety,” he said.“I could see that Christine was very anxious and shaken more than I have ever seen.”Alisdair Smith, prosecuting, said: “The motivation appears to be a belief that there’s a form of bond or pre-destined emotional relationship and comments made by the complainant on television.“This is an allegation of a sustained period of harassment.”Video: Christine Lampard talks about stalker on Loose Women Want the best of The Telegraph direct to your email and WhatsApp?
