She also alleged that like the previous Congress government, the BJP dispensation too is using the CBI, ED and the Income Tax department against its political opponents for electoral gains.
"Under such circumstance, the electorate have to see to it that neither the BJP nor the Congress... comes to power at the centre," the BSP chief said at an election meeting here.
Claiming that the BJP will be voted out of power this time because of its pro-RSS, capitalist, communal and casteist policies, Mayawati said no amount of "drama" or 'jumlebazi' (rhetoric) will help the party.
"The borders of the country are not totally secure under the BJP government as a result of which terror attacks are taking place and several jawans are being martyred. It is most unfortunate that they are anyhow using this for election purposes," the BSP supremo said.
"The new 'dramebazi' of 'chowkidar' will also not be able to save them (BJP) even if all their big and small 'chowkidars' (watchmen) get together and make an all out effort," she said.
Warning people that her political opponents have "adopted every trick" to win the elections, Mayawati said people should not fall for tall election promises and allurements.
"During the last Lok Sabha election, the prime minister (Narendra Modi) had the country dream of 'achche din' and made promises even one-fourth of which were not fulfilled. This is because most of their time was devoted to saving their capitalists friends and making them richer," she claimed.
The BSP president also accused the Congress of ignoring the contributions of B R Ambedkar and said like the implementation of the Mandal Commission report, Bharat Ratna was awarded to the architect of the Constitution only when V P Singh was the prime minister.
"When V P Singh sought our support for his government, we put forth two conditions -- Bharat Ratna for Ambedkar and implementation of Mandal Commission report, which he accepted. But the BJP, which was giving outside support, did not like this and withdrew," she said.
