Its not as easy as it seems... SP is playing a bigger game.
SP knows, BJP has a strong chance in UP elections.
Therefore, they ve a create a B party, in case if BJP gets high seats, akhilesh can align with congress, backed by BSP as well.
And in case, SP gets gud no of seats, mulayam will say " after son will be son", so he is invited back in
Basically, they dont want to fight the election in coalition ( SP+CONG+BSP), I mean before d election....
but want the option open open for coalition after elections.
everything is being done to counter BJP. :k
