"Don't two brothers fight over property, same way both BJP governments are fighting over Mhadei," he said reacting to Goa's stand on the Mhadei river water dispute.
Both the states are locked in a dispute over sharing of Mhadei river water, which originates in Karnataka and meets Arabian Sea near Panaji in Goa.
"What they (Karnataka) are doing is right because they are defending their rights," Parrikar said, adding that as a chief minister, he would be fighting for the interest of Goa.
On whether he will try to work out an amicable situation over the dispute, Parrikar said irrespective of party affiliations, any government in Karnataka will have the same approach towards Mhadei river diversion.
"Their attitude would be the same," he said.
Goa has approached the Supreme Court demanding adequate resources for the inter-state water dispute tribunal, which is likely to take up the issue, Parrikar added.
