Not good for an election year: British Prime Minister Gordon Brown is reportedly so verbally abusive that several members of his staff have called an anti-bullying hotline, according to the CEO of the National Bullying Helpline. She came forward after the release of a bombshell new book by journalist Andrew Rawnsley, The End of the Party, which describes the prime minister's volcanic temper and tendency to fly into rages and yell at his staff. Downing Street staff and business secretary Lord Mandelson denied that Brown had temper issues. Rawnsley's book describes Brown roughly shoving aside one longtime aide and grabbing another office worker by the lapels after he made a mistake. "He suffers from a massive paranoia and an inability to accept blame, yet he runs a blame culture that allows him to blame others," a former adviser told The Guardian.
