Michael Jackson's former physician Conrad Murray has filed court papers indicating that he plans to appeal his involuntary manslaughter conviction over the singer's death and his four-year jail sentence.
His lawyers filed the papers with the Los Angeles Superior Court in a precursor to a formal appeal being lodged with a California Appeals Court.
Murray was convicted last month of involuntary manslaughter, after admitting that he gave the pop star nightly doses of the anaesthetic propofol in June of 2009 to help him sleep.
He was sentenced to four years in jail by a Los Angeles judge who called him a "disgrace to the medical profession".
Jackson, who was 50, died in Los Angeles on 25 June 2009.
His death came just weeks before a planned series of comeback concerts in London.
