Brazil's Lula must start prison term, Supreme Court rules

Former Brazilian President Luiz Inácio Lula da Silva will be imprisoned while he appeals his corruption conviction, the country's Supreme Court has ruled.

He is facing 12 years in prison on charges of accepting a bribe.

Lula claims the charges are politically motivated, and designed to prevent him from running in October's presidential election.

Polls suggest he is the top candidate in the race, but being sent to jail could jeopardise his campaign.
