(3) The Ittefaq had the largest

The Ittefaq had the largest circulation of all other dailies in Bangladesh.

What about the sentence? Is it correct?

Hi,

I would say: all the other dailies, or simply ‘all the dailies’.

The Ittefaq had the largest circulation of all the dailies (daily newspapers) in Bangladesh.

‘other’ is not needed. You are comparing them all, including the Ittefaq.
