In an ultimatum to Mulayam Singh Yadav over the Azam Khan issue, SP leader Amar Singh has threatened to quit the party after the Lok Sabha polls, accusing the Muslim leader of making 'intolerable utterances' against him.

Singh said he would decide over continuing in the party after the end of the final phase of polls, referring to Yadav's statement that party mein rehna hai to Azam Khan ko khush rakhna hai (If you want to remain in the party, you will have to keep Azam Khan happy).
