The deal, for an undisclosed sum, follows a strategic partnership formed last year, whereby each company recommended the other to its own clients (PRWeek, 2 August 2002).
Tavistock chairman Jeremy Carey said both firms would retain their separate identities, but that City Insights director and co-founder Simon Hudson will join the board of Tavistock.
Hudson said no City Insights staff will lose their jobs following the acquisition. This includes its director team of Nigel Utley, Tony Cooper and Axel Tan, as well as support staff. Utley is a former head of research at broker Greig Middleton.
Hudson says that clients which both Tavistock and City Insights teams will work on include Berkeley Group, Benchmark Group and Prelude Trust.
According to last year's PRWeek financial PR league, which is based on the total value of deals handled, Tavistock is ranked 17th (PRWeek, 25 October 2002).
Last month it handled a number of transactions for long-term client Vodafone, including the mobile phone firm's deal with Portuguese telecoms group Vodafone Telecel-Comunicacoes Pessoasis (PRWeek 14 March).
