Karnataka's PWD Minister and senior JD(S) leader HD Revanna on Thursday said he will quit politics if Narendra Modi got re-elected to become the prime minister again.

"I will retire from politics if Modi gets re-elected from Varanasi and becomes Prime Minister again. The BJP will not come to power this time," Revanna told reporters at Hassan, about 150 km away from Bengaluru.

Revanna, second son of JD(S) supremo HD Deve Gowda and elder brother of Chief Minister HD Kumaraswamy, is in the city to campaign for Congress candidate CH Vijayshankar, contesting against outgoing BJP member Pratap Simha from the Mysore Lok Sabha seat.

"Our party JD(S) has joined the Congress as a pre-poll alliance to bring the UPA back to power and keep the 'communal' BJP out as we have to protect the interests of distressed farmers across the country," said Revanna.

"I would like to know what Modi has done for farmers in the last 5 years. Though the state government sent a list of 15 lakh farmers to the central government for including them in the PM Kisan Samman Nidhi Yojana, Modi claimed that the Centre was yet to receive it. This is a lie," said Revanna.

Lok Sabha elections in Karnataka will be held in two phases of 14 seats each.

Polling will be held on April 18 in Udupi-Chikkamagaluru, Hassan, Dakshina Kannada, Chitradurga, Tumakuru, Mandya, Mysuru-Kodagu, Chamarajanagara, Bengaluru Central, Bengaluru North, Bengaluru Rural, Bengaluru South, Chikkaballapura and Kolar.

The remaining constituencies of Chikkodi, Belagavi, Bagalkote, Bijapur, Gulbarga, Raichur, Bidar, Koppal, Ballari, Haveri, Dharwad, Uttara Kannada, Davangere and Shivamogga will vote on April 23.
