John Buchanan quits Vodafone but denies row

SIR John Buchanan is preparing to step down from the board of Vodafone where he has served as deputy chairman since July 2006.

Sir John, who is also chair of medical devices business Smith and Nephew, will replace Doug Dunn as chairman of Cambridge-based chip maker ARM Holdings on 3 May.

He has sat on the telecoms giant’s board since April 2003, meaning he has reached the nine-year threshold and is no longer considered an independent board member.

Despite reports to the contrary, the telecoms group vehemently denies that Sir John’s departure is related to a clash with Vodafone boss Vittorio Colao over a possible bid for Cable & Wireless Worldwide, claiming that Sir John has not voiced an opinion about the potential takeover.
