A controversy erupted over the induction of former BSP MLA Jitendra Singh Bablu into the BJP on Wednesday, with party MP Rita Bahuguna Joshi alleging that he was involved in the torching of her house in July 2009 and demanding the cancellation of his membership. Besides Mr Bablu, some other leaders of the BSP and the Congress also joined the BJP at the party headquarters in Lucknow in the presence of state unit president Swatantra Dev Singh.
