It has reported half-year operating profit of £101m, a 31 per cent year-on-year increase on the back of acquisitions, positive currency translations and the strength of its overseas operations. Organic, constant-currency growth was still good at 8 per cent, thanks to a 50 basis point increase in the operating margin to 23.6 per cent.
