Three months after proposing a complete overhaul of the non-profit group charged with overseeing technical matters related to the Internet's addressing system, ICANN president and chief executive officer Stuart Lynn said that he will be leaving the agency next March, in order to focus on his personal life and health.
Lynn took over his post at ICANN in March 2001, under a two-year contract.
Additionally, ICANN vice-president and chief policy officer Andrew McLaughlin said that he will be leaving on 1 July to return to Harvard Law School's Berkman Center for Internet and Society.
McLaughlin will continue to work part-time at ICANN to facilitate a smooth transition, the group said.
McLaughlin began working with ICANN in 1999 as a senior advisor and staff member until he eventually took the post of vice-president.
In a statement, ICANN board member Vint Cerf said that the board was disappointed with the news, but understands the motives behind the departures. Cerf added that the board will organise a search committee to seek Lynn's replacement.
