Bumi row is stoked up

The financier Nat Rothschild has escalated his row with the board of Bumi, after claiming that the latest results from a key subsidiary of the Indonesian coal miner he co-founded lacked credibility.

Bumi Resources, in which the parent company Bumi owns a 29 per cent stake, announced a $632m (£388m) loss for the first nine months of 2012, compared with a $175m profit a year earlier.
