LUCKNOW: Samajwadi Party supremo Mulayam Singh Yadav on Tuesday charged CBI with bothering him a lot but said he came out clean and now he was a "CBI-certified honest" person."The person who progresses from poor section of the society has to face such (CBI probe) problems. All persons should keep their papers and accounts updated otherwise CBI will frighten them," he said.Yadav was addressing a gathering at party office here on occasion of Maharshri Kashyap Nishadraj Guha anniversary."CBI bothered me a lot. It searched my house and also of my relatives for disproportionate assets. Fields and cattle were also counted but they got nothing. In such scenario I can say that now I am CBI-certified honest," he said.CBI had in 2013 cleared Yadav of charges that he misused his office as chief minister of Uttar Pradesh to accumulate vast amounts of wealth.It had closed the case that began in 2007, ceding that there is "grossly insufficient evidence" against the chief of the Samajwadi Party.Attacking Prime Minister Narendra Modi, he said his promise of giving Rs 15 lakh to every person after getting back black money stashed away in foreign banks and jobs to unemployed remained unfulfilled."Those who used to talk about chasing away Pakistanis are now shaking hands with them and Modi had invited their PM Nawaz Sharif for his oath taking ceremony," he said.He claimed that when Modi was shaking hands with his Chinese counterpart, his army was sneaking into Indian territory and when he raised the matter in Lok Sabha a hue and cry was raised and they (Chinese) had to back track.The SP supremo said that for including 17 backward castes in SC category, there was a need to hold a big conference in Delhi.
