Britney Spears has told an LA court that she wants her father charged with conservatorship abuse.

Addressing the court for the second time in less than a month, Spears demanded once again that Jamie Spears be removed from the legal agreement that has controlled most of her life for more than 13 years.

Giving evidence by phone, as supporters of the #FreeBritney movement protested outside the hearing, the star initially said she wanted the courtroom cleared, before changing her mind and saying she would speak publicly.

She listed a series of grievances, including that her hair vitamins and coffee had been taken from her. "Ma'am, that's not abuse, that's just f****** cruelty," she tearfully told Judge Brenda Penny. "Excuse my language but it's the truth."

After taking a short break to compose herself, Spears, 39, called for her father be removed from the complex legal arrangement and be charged with "conservatorship abuse".

The singer said she wants the conservatorship terminated without the need for a medical assessment, but made it clear her top priority was ousting her father from his role. She said she would be happy allowing co-conservator Jodi Montgomery to remain in the meantime.

"My dad needs to be removed today and I will be happy with Jodi helping me," the star said.
