Shivsena (UBT) leader Tejaswi Ghosalkar, a former BMC corporator and widow of the late Abhishek Ghosalkar, has joined the Bharatiya Janata Party. This move, ahead of the upcoming BMC elections, is seen as a significant setback for Shivsena (UBT) and a potential electoral advantage for the BJP in North Mumbai's influential Ghosalkar family stronghold.
