Brazil oil auction: Lone bid wins exploration rights

22 October 2013 Last updated at 01:51 BST

The rights to explore Brazil's biggest oilfield have been won at an auction - by a consortium led by state-run Petrobras and backed by Total, Shell and Chinese firms.

The group made the only bid in the auction, offering the minimum share of the surplus production.

Earlier, striking oil workers opposed to the sale clashed with police, as Wyre Davies reports.
