Bengaluru: Senior BJP leader R Ashok on Saturday demanded the resignation of Karnataka chief minister HD Kumaraswamy and Congress Legislative Party (CLP) leader Siddaramaiah from their posts after the ruling coalition's dismal performance in the Lok Sabha election in Karnataka.

Referring to his party's win in 25 of the 28 seats in the state, Ashok, the former deputy chief minister, said it meant people voted for it in more than 177 assembly segments.

"People have given us massive support. They have voted for BJP in more than 177 assembly segments out of 224. It means Kumaraswamy and CLP leader Siddaramaiah must immediately step down from their positions," he told reporters.

His demand came a day after the Karnataka cabinet on Friday reposed its "faith and confidence" in the leadership of Kumaraswamy, asserting that the coalition would continue.

Mocking Siddaramaiah, Ashok, said the former chief minister was the chairman of the ruling coalition's coordination committee, but the panel lacked coordination.

"People saw how Siddaramaiah coordinated in Tumakuru and Mandya to ensure the defeat of JD(S) candidates (HD Deve Gowda and his grandson Nikhil Kumaraswamy), said Ashoka.

In a shocking outcome, Nikhil Kumaraswamy, son of state chief minister HD Kumaraswamy, lost to independent and multi-lingual actress Sumalatha, wife of late Congress MP and actor Ambareesh.
