Kolkata: West Bengal Pradesh Congress Committee President Adhir Ranjan Chowdhury on Thursday called on to make the Bangla Bandh scheduled on 18 August successful. The differences between Adhir and Congress leader Manas Bhuiyan came to the forefront over the fixing of dates of the Bandh. Manas Bhuiyan had written to the Congress High Command asking a change in the date of the Bangla Bandh which has been rejected by the high command. As a result the bandh stays fixed on August 18. Adhir Chowdhury has cleared the air saying that Bandh will be held on 18 August only.
