Mumbai: Stating that 90 per cent of the banking activity in Maharashtra is concentrated in Mumbai, adjoining Thane and Pune, Chief Minister Devendra Fadnavis today asked bankers to form a working group to ensure that the services are more broad-based, so as to boost growth.

Chairing a special meeting of the State Level Banking Committee, Fadnavis asked the banks to study the pockets which do not have any branches, an official statement said.
