This story is fabricated by CPM agents in the media. Samajvadi Party is almost getting attacked by Mayavati in UP left right and centre. To survive, SP immediately needs the help of Congress in Centre to slow down the CBI cases, and alliance with Congress in UP to contest next parliament elections. Otherwise Mayavati will finish off SP. SP is frantically trying to prevent this.
Getting a few minister posts in Centre for a year will definitely boost the prospects of SP, which is out of power for quite some time.
The guy Munawwar Hasan doesn't see any future in SP and he is going to join BSP. So Mulayam will not listen to him.
