The Bell Pottinger and Good Relations groups notched up fee income of £30.8m in the year to December 2002.
In second place is Incepta's Citigate - including Dewe Rogerson and the group's Scottish and Northern Irish operations - having slumped by 25 per cent on last year's figures to £23.4m.
Third is Edelman, which registered fees in 2002 of £14.5m.
The rest of the top five are College Hill, with a fall of two per cent to £7.9m, and The Red Consultancy, which grew fees 16 per cent to £7.7m.
Last year's number one, Weber Shandwick, is - in common with PR arms of six major quoted groups - absent from the 2003 table due to fresh US disclosure rules.
The fastest growing agency in the Top 150 is Geronimo, which grew fee income by 148 per cent to £1.9m.
