Samajwadi Party chief Akhilesh Yadav on Friday slammed the BJP-led government at the Centre for misusing central agencies to "harass leaders and public representatives of opposition parties", who pose a threat to the saffron camp. Yadav, who is in the city to chair his party's two-day national executive, is scheduled to meet West Bengal Chief Minister and TMC supremo Mamata Banerjee on Friday evening in Kolkata.
