Temporary power firm Aggreko has seen currency headwinds hit its profits in the first half of the year.

The Glasgow company said the strong pound was a major contributor to the nine per cent dip in pre-tax profits to £132 million.

Group revenue edged up one per cent from £760 million to £768 million.

Aggreko said it still expects to deliver full-year profits in line with last year.

This boosted shares, with the stock up three per cent, or 50p, to 1771p.
