The result of next general election will be a hung parliament, with UPA, NDA & third front winning almost equal seats. Since UPA is already in power, it will not have any moral right to continue. Then, history will repeat itself & UNPA/NDA will have power sharing agreement. As per this, first Mayawati will be PM for 2 1/2 years & when Advani's turn comes to get the throne, Mayawati will ditch him as done in the past by her in UP. And there will be elections & Congress will again come to power.
