After targetting his former mentor Bal Thackeray for years and facing the brunt of Shiv Sena anger, NCP leader Chhagan Bhujbal has buried the hatchet. He withdrew a defamation case he had filed against Thackeray in 1997. "The Sena leadership wrote to me asking me to withdraw the case because of Balasaheb's ill health and I agreed," said Bhujbal.
