Science chief urges badger cull

The UK government's chief scientist advised ministers that badgers should be killed to prevent the spread of TB among cattle, the BBC has learned.

Sir David King says culling could be effective in areas that are contained, for example, by the sea or motorways.

His report follows a previous study that said culling badgers would be ineffective.

The Independent Scientific Group found that targeting one site would only cause badgers to flee to other farms.

Sir David told the BBC "now is the time for action".
