Rolls-Royce warns profits could fall further

London - British engineer Rolls-Royce has warned profits this year could fall by as much as 13% on top of an 8% drop last year, saying the low oil price had increased uncertainty for many of its markets and customers.

The world's second-largest maker of aircraft engines after US group General Electric had already cut its 2015 forecasts in October, when it shocked the market by warning there would be no growth this year.

The company said on Friday it now expected to make a pretax profit of £1.4 to £1.55bn in 2015, a drop of up to 10 percentage points on its previous forecast in October for profits to be up to 3% lower.
