Freewill of Bangalis was considered a threat just like it is now for Sindh, Balochistan and NWFP.

In 1966 Mujib announced his controversial six-point political and economic program for East Pakistani provincial autonomy. He demanded: -

1. The government be federal and parliamentary in nature, its members to be elected with legislative representation on the basis of population,
   
2. The federal government have principal responsibility for foreign affairs and defense only,
   
3. Each wing have its own currency and separate fiscal accounts,
   
4. Taxation would occur at the provincial level, with a federal government funded by constitutionally guaranteed grants,
   
5. Each federal unit could control its own earning of foreign exchange; and
   
6. Each unit could raise its own militia or paramilitary forces.
   

Mujib's six points ran directly counter to President Ayub's plan for greater national integration. Mujib was arrested in January 1968.
