Coming down heavily on the UPA government at the Centre which his party helped survive after the Left withdrew its support over the Indo-US nuclear deal, Samajwadi Party chief Mulayam Singh Yadav has charged it with using the CBI to try and put him behind bars.

"The government, which we have supported during the height of the Indo-US nuclear deal imbroglio, is now trying to send me to jail with CBI's help," the former Uttar Pradesh Chief Minister told a function at Charan Singh PG College here on Thursday.
