Uttar Pradesh Legislative Council Member (MLC) Udayveer Singh was on Saturday expelled from the ruling Samajwadi Party (SP) for six years. Udayveer had courted controversy by writing a letter to SP President Mulayam Singh Yadav, asking him to step down from the party post in favour of his son and Chief Minister Akhilesh Yadav. Party sources said the leadership did not take kindly to the “caustic letter” by the young leader, considered close to Akhilesh and whose association with the latter dates back to the Dholpur school days.
