The Hemscott Adviser Rankings for financial PR up to the end of the May, showed Brunswick extending its lead over Finsbury for FTSE 100 clients from seven to nine. FD was the only other firm in double figures, with Maitland slipping back to single figures after losing 3i to Finsbury.
But figures seen by PRWeek for clients by profit and by market cap, show Finsbury in edging out Brunswick on both measures for both FTSE 100 clients and total clients.
Finsbury's total listed clients are worth £489bn, compared to Brunswick with £472bn. FD at £354bn and Maitland at £195bn are the other agencies over the £100bn mark. Tavistock Communications is just below that threshold with £99bn.
Finsbury's clinets made £62bn in profit, overtaking Brunswick which saw its clients make £58bn.
FD has the most clients in the industry with 167, followed by Buchanan Communications and Pelham Bell Pottinger with 85 and 84 respectively.
