Britney 'not fit' for probate trial

Troubled pop star Britney Spears is not yet fit to participate in court proceedings in her power-of-attorney case, her lawyer told a superior court commissioner.

Samuel Ingham, Spears' court-appointed lawyer, and lawyers for her father and conservator, James Spears, spent 90 minutes in Los Angeles commissioner Reva Goetz's chambers.

Mr Ingham told the court afterwards that Spears' medical condition was "fluid" because her treatment was changing.

Spears' probate case is due to go to trial on July 31, but Mr Ingham said it could be "harmful" for her to participate.

Ms Goetz agreed and said Spears' diagnosis was not complete.

The 26-year-old singer and her estate have been under the conservatorship of her father for four months.
