Lucknow, Apr 15 (IANS): The ruling Samajwadi Party (SP) in Uttar Pradesh Monday cautioned BSP leader Mayawati and told her to control her diatribe against SP workers.

Public Works Department Minister Shivpal Singh Yadav said: "She is saying all sorts of things about our party workers. She should remain calm."

Shivpal Singh, the younger brother of SP chief Mulayam Singh Yadav, added that "it would be difficult to control SP workers" who are enraged by Mayawati's comments.

At a public rally here Sunday, Mayawati had warned SP workers and threatened them of dire consequences if her party was voted back to power. She had said that "SP goons would be thrashed black and blue".

The SP trashed charges of political vendetta levelled by former chief minister Mayawati and said had it been the case she would have been behind bars.

Shivpal Singh said that instead of slamming the SP, the BSP leader should introspect on why her party lost in the assembly elections in 2012.
