A group of lawmakers who have shaken up the coalition government in Karnataka have been at two luxury hotels in Mumbai since Saturday. While the BJP has denied any role in their resignation from the Congress-Janata Dal Secular coalition, its leaders were sighted in both the hotels. Eleven lawmakers of the Congress and JDS, who resigned on Saturday, were flown to Mumbai by special charter and put up at the Sofitel. The bunch was moved later to another hotel, Renaissance.
