Singer Britney Spears won the right to choose her own lawyer to help her end a 13-year-long conservatorship and tearfully pleaded for the court to oust her father immediately from the role of controlling her business affairs. Her father, Jamie Spears, has been a major figure in the conservatorship since he set it up in 2008 when his daughter had a mental health breakdown. He is currently the sole person in charge of her $60 million estate. “You’re allowing my dad to ruin my life,” Spears told the Los Angeles judge by phone.
