NEW DELHI, Feb 10 (Reuters) - Indian billionaire Gautam

Adani on Monday said his family will invest over 60 billion

rupees ($686.18 million) to launch two affordable health

campuses in Mumbai and Ahmedabad in consultation with the

U.S.-based Mayo Clinic.

Each campus will have hospitals, medical colleges,

transitional care and research facilities, with technical

expertise provided by the not-for-profit Mayo Clinic Global

Consulting, according to a statement from the Adani group.

Adani said the health campuses were the first projects to

come from a 600 billion rupee-pledge towards healthcare,

education and skills development made two years ago.

The Adani group is also revamping Asia's largest slum into a

modern city hub. But the $619 million deal to redevelop Mumbai's

Dharavi slum has faced opposition from residents over its

capacity to deliver.

In November, U.S. authorities accused founder Adani and some

top executives of being part of a scheme to pay bribes worth

$265 million to secure Indian power supply contracts. The Adani

group has called the charges "baseless".
