At least two-thirds of the candidates for the Bangladesh Chhatra League (BCL) central committee office-bearers to be elected by the April 3-4 national council are near 40 in age and left behind their student life long ago. The student wing of Awami League (AL) has held only three national councils in the last 12 years, saturating itself with a huge number of aged and non-student 'student leaders', sources said. As a result, there is now a severe leadership crisis at all levels, from the centre down to the grassroots units, of the country's leading student body.
