Kohtes Klewes parent firm The European Communications Consultants, headed by Gregor Schonborn, maintained its position in the top slot, increasing its turnover by six per cent to £20.6m, excluding subsidiary ECC Publico.
A newcomer in second place with £12m in fees is Weber Shandwick, which merged with BSMG Worldwide in October last year.
Third place went to last year's runners-up, Trimedia Communications.
The largest leap was made by Fleishman-Hillard, which grew 61 per cent, leaping 11 places since last year to tenth place.
