Apple boss Steve Jobs received a liver transplant about two months ago and is expected to return to work later this month, a US newspaper has reported.

The Wall Street Journal said the Apple chief executive would be returning to his job on schedule, but may initially work part-time.

Neither Mr Jobs nor a company spokeswoman confirmed the report, the newspaper said.

Mr Jobs ceased his normal management role more than five months ago.

In January, he announced that he was being treated for a "hormone imbalance", and had been losing weight throughout 2008.
