NEW DELHI, MARCH 20: Exactly five months after his assertion that ``no political equation in Delhi could be worked out without him'', Bahujan Samaj Party leader Kanshi Ram, after his defeat in the Lok Sabha elections, declared here today that he will not contest any election in the next five years.He also accused Uttar Pradesh Chief Minister Kalyan Singh and other senior BJP leaders for ``settling political scores'' by implicating former chief minister Mayawati in the Rs 3.66 crore contract for supply of floating pumps to rural fire stations in the state.The Central Bureau of Investigation, which filed an FIR against Mayawati, did not mention the role being played by the then DGP (Fire fighting), state fire fighting director Lalit Srivastava and Sunanda Prasad, a senior IAS officer, he alleged.Asserting that he will continue to fight against corruption and criminalisation of politics, especially in Uttar Pradesh, the BSP leader, for the first time after the debacle of his party in the Lok Sabhaelections told The Indian Express that he will confine his movement among the Scheduled Castes (SC) and Other Backward Classes (OBCs).Maintaining that he had ``overestimated the BSP's clout over the Dalits and the OBCs'' the BSP chief said that starting with a meagre vote share of 2.4 per cent in the 1985 Assembly elections in UP, his party had grown to a sizeable presence in the successive elections in 1989 (eight per cent), in 1991 (nine per cent) and in 1996 (20 per cent).``Rajnitik shakti ke bina samajik parivartan nahin laya ja sakta hai. Abhi samajik nyay ke liye BSP ko aur mehnat karni hogi (There can be no change without power. The BSP will have to work harder),'' Kanshi Ram said while accepting his party's defeat in the elections.He accused the BJP of having offered the Home portfolio to Mayawati and a sum of Rs 5 crore to some of the other party MPs to secure their support during the crucial trial of strength on the floor of the House on March 29. He said: ``Senior party leaders LaljiTandon and Kalraj Mishra, close associates of Vajpayee, had approached Mayawati in this connection five days back.''``Not only this,'' he stated, ``Kalyan Singh had also got in touch with Akbar Ahmed Dumpy, newly elected BSP MP from Azamgarh, and had offered him a ministerial berth if he abstained from voting during the crucial trial of strength.''Terming the BJP a ``corrupted'' party, he said it was protecting and patronising criminals in the state and had also provided them ministerial berths in the state Cabinet. ``I will fight against such forces till my death,'' he said adding that ``the Kalyan Singh government was installed with the help of purchased legislators.''Meanwhile, coming down heavily on the CBI for accusing Mayawati of favouring her party activist Devanathan by awarding him a Rs 3.66 crore contract for the supply of floating pumps at rural fire stations, he said the CBI, on the instruction of the BJP government in the state had implicated her to tarnish her political image.TheCBI, in its FIR alleged that Mayawati, in her capacity as chief minister, had personally cleared the floating pump project in favour of Fire Challenger despite knowing that the company had earlier been blacklisted for supplying sub-standard materials and that an adverse inquiry was pending against Devanathan with the Tamil Nadu Vigilance department.
