Last week the mining giant, which listed in 2011 at 530p, announced plans to cut capital expenditure for the second half of the year by as much as $800m (£513m).
The company is expected to post results showing a net income of just $780m, down from the $2bn it made in the same period last year. The company has been hit hard by the Chinese devaluation, as well as plummeting prices of copper and oil, its main profit drivers.
Meanwhile, the FTSE was also dragged down by supermarket Morrisons, after stories in the press over the weekend suggested it was hatching a plan to sell off its convenience stores. Shares in the supermarket chain fell 0.81 per cent to 176.3p
