Puducherry Chief Minister V Narayanasamy pulled off an all-nighter and slept on the road outside Lieutenant Governor Kiran Bedi's residence in the latest case of power struggle between the Union Territory's Congress government and the former IPS officer. What triggered the protest was Ms Bedi's idea of making wearing helmets compulsory for motorists with immediate effect. Mr Narayanaswamy, however, was against it and wants the rule to be implemented it a phased manner.
