Aimed at targeting the ruling Congress, Karnataka BJP president B Y Vijayendra on Saturday announced a day and night protest against price rise from April 2, and a statewide awareness campaign after April 10 against the government's "unconstitutional" move to provide a 4 per cent reservation for Muslims in public contracts. He also said that the party will hold a protest against the suspension of 18 BJP MLAs from the Assembly, calling Speaker U T Khader's decision as "dictatorial".
