Leeds-based Wrigleys was created in 1996 when Dibb Lupton Alsop off-loaded its private client department. Since then it has been joined by the private client practices of Hammond Suddards and Eversheds in Leeds.
It has now taken leading charity specialist Malcolm Lynch under its umbrella.
Two partner Malcolm Lynch has five fee-earners and is headed by name partner Lynch. It is regarded as the leading charity practice in the North East and Lynch himself is regarded as one of the most highly ranked practitioners in the region.
Clients include the Earth Centre, the Charities Aid Foundation, the Diocese of Ripon and Leeds and the Institute of Mining and Mechanical Engineers.
The move will therefore considerably bolster Wrigleys' standing as a major player in charity work.
Lynch says: "We are losing our name but the reputation of the firm carries on into Wrigleys. We are now even more of a formidable challenge to the London firms."
Wrigleys senior partner Martin Wrigley adds: "Charities are demanding an increasingly sophisticated legal service. Our cultures and development strategies are similar so the merger makes sound business sense."
