Ties between the Congress and the BSP have warmed up in past months - a development that has provoked SP chief Mulayam Singh Yadav's new-found antagonism against the UPA.
For different reasons, the SP and BSP - both outside supporters of the UPA - are not in favour of early polls.
While Congress managers realise that a formal alliance with either the SP or the BSP is not possible, they have been in close touch with BSP chief Mayawati in past months.
Given her strength to ensure complete transferability of her core vote bank, BSP is considered a better ally for the Congress after the 2014 polls.
The Congress also sees Mayawati - who is presently out of power - as a lesser political threat; while Yadav has been floating the concept of a third front every now and then.
The law and order scenario in UP has rapidly deteriorated and the SP's support base amongst the Muslims has dwindled.
"The Akhilesh government needs time to undo the political damage, but is wary about the emerging bonhomie between the Congress and BSP," a senior SP leader conceded.
The BSP, however, hopes to reap richer political harvest in the event of delayed elections.
