Ahead of the Presidential polls, Shiv Sena has replaced its chief whip in the Lok Sabha. In a letter written to Lok Sabha Speaker Om Birla, Shiv Sena's Rajya Sabha MP Sanjay Raut has said that the party has nominated Mr. Rajan Vichare as the chief whip in place of Mrs. Bhawana Gawali with immediate effect. This comes a day after Shiv Sena MP Rahul Shewale urged party president Uddhav Thackeray to support NDA's candidate Droupadi Murmu for the presidential polls.  Relations between Shiv Sena and NDA, led by BJP have soured in the past three years after a disagreement over government formation in Maharashtra. The fissures have aggravated over the last two weeks during which the Uddhav Thackeray-led MVA government was toppled after a rebellion by 40 Shiv Sena MLAs.
