Bird & Bird chairman Massimiliano Mostardini will not face re-election this year, it has emerged, as the firm's partnership has extended his tenure so that it does not coincide with the managing partner's term.

Mostardini, who had been expected by many to be up for a partner vote this March, will serve a four-year term and face re-election next March instead. The length of the term will then return to three years, ensuring chief executive and chairman elections are out of sync moving forward.

Mostardini was appointed as chairman in 2016, replacing veteran Michael Frie, who had been chairman since 2007. Current CEO David Kerr was re-elected at the same time, extending his time at the top to more than two decades, and making him one of the longest-serving leaders of a UK law firm. Kerr took over as Bird & Bird CEO in 1996.

A Bird & Bird spokesperson said the change to the term was made in 2017 as part of a "more extensive governance review", but would not give further details.

Mostardini is a well-established presence within Bird & Bird, having set up the firm's Italy practice and served as managing partner since 2003. One former partner described the chairman as a "flamboyant" figure within the firm.

Putting the chairman and CEO roles out of sync means there is no prospect of an entire management change simultaneously in the future.

Such an event nearly occurred in 2016, according to one former Bird & Bird partner, who was at the firm as the changes were voted in. They said the decision to introduce the transitional measure followed the 2016 CEO election in which longstanding chief David Kerr did not secure a majority vote in a "two-horse race" against Dominic Cook, who at the time was head of Bird & Birds' consultancy spin-off Baseline.

The ex-partner said that in 2016 the majority of the partnership either voted against Kerr or abstained, meaning Kerr ended up winning without a majority of the vote. This led to the 2017 amendments as a precautionary measure, the individual said.
