A US judge has denied Britney Spears's request to remove her father from his role overseeing her conservatorship.

Axar.az reports that the pop star's lawyer asked an LA court to end Jamie Spears control of her estate, in November last year.

They said the star was "afraid of her father" and wanted him removed as her sole conservator - a role he has carried out since 2008.

Although the request has been denied, the ruling is not a response to Spears' explosive testimony in court last week.

Speaking for 23 minutes, the star said she had been drugged, forced to perform against her will and prevented from having children.
