Samajwadi Party (SP) leader Kasim Raeen on Friday resigned from all party posts citing "no action" by party chief Akhilesh Yadav and others against "rising incidents of atrocities meted out to Muslims" in Uttar Pradesh.

In the resignation letter shared by Raeen, he accused the party chief of inaction and questioned his silence over the incarceration of Azam Khan and his family.
