Michael Jackson has reportedly been ordered to confirm his Christmas visit to Britain or surrender his passport.

The singer, who is charged with child abuse in the US, has been told to supply "documented confirmation" for his UK trip.

He received the demand from Tom Sneddon, district attorney for Santa Barbara county, in California, reports the BBC.

Mr Sneddon said he wanted confirmation of the visit after reports that it had been cancelled by the pop star.

Jackson's spokesman has said the trip to promote his new CD is still on. Mr Sneddon made the demand on Monday in a faxed letter to the star's lawyer, Mark Geragos.

Mr Geragos has said his client needs to visit Britain to fulfil contractual obligations related to his compilation CD, Number Ones.

Uri Geller has warned his friend not to travel to the UK because the media would "tear him apart".
