The dispute between Reliance Infra- led Mumbai Metro One and the state is set to intensify with Maharashtra Chief Minister Devendra Fadnavis saying his administration will challenge the proposal to increase fares up to Rs 110 for the 11.4-km metro service, in the Supreme Court.

The FFC (Fare Fixation Committee) has recommended a tariff structure of Rs 10-110 for the Versova-Andheri-Ghatkopar Metro, which is an over threefold increase over the present fare of Rs 10-40.
