Finsbury jumped five places to number one in the Deal Watch table for April. It benefited from oil giant Royal Dutch Shell's sale of its InterGen NV power plant business, and Standard Chartered's acquisition of Korea First Bank.
Finsbury also advised French drinks company Pernod Ricard on its £7.4bn takeover of Allied Domecq.
The same deal pushed College Hill into the top ten for the first time since February. It also worked on Old Mutual's sale of a minority stake to the Brimstone Investment Corporation.
Although Citigate Dewe Rogerson and Brunswick fell to third and fourth respectively, the value of the deals they advised on almost doubled last month.
Brunswick advised aerospace firm United Technologies Corporation on its £1.35bn acquisition of aircraft safety systems supplier Kidde, which used Finsbury.
Lansons Communications was another high riser, coming eighth, while Buchanan Communications remained seventh. Both worked on Life Company Investor Group's £1bn buyout of HHG's life insurance arm.
The Hogarth Partnershp, Cardew Chancery and M: Communications all fell out of the top ten for April's rankings.
