Dispute in Venezuela over Chavez not taking an oath

Venezuelan President Hugo Chavez will not take the oath for a new term in office on Thursday, the government has said.

Mr Chavez is in hospital in Cuba after cancer surgery, and has suffered complications caused by a lung infection.

He has not been seen in public since his operation last month.

Venezuela's opposition has called for the Supreme Court to rule on what should be done if Mr Chavez is absent.

Sarah Grainger who is in the Venezuelan capital, Caracas, explains the implications of the crisis.
