Tribute to Mark Whittaker

Mark Whittaker, presenter of World Business Report and Business Matters, and a BBC stalwart for 30 years, has died at the age of 57. World Service Business Editor Martin Webber pays tribute to Mark's extraordinary talents and great humour, and introduces a piece Mark filed earlier this year from Japan; a visit to an island where centuries-old traditions are threatened by Japan's shrinking population. Mark will be very much missed by the team.
