"The person who was to address the rally is in the Z-plus security cover category and despite that there was no proper security arrangement," BJP national spokesperson Meenakshi Lekhi told reporters here.
Blaming intelligence bureau and the CID in Bihar for 'complete intelligence failure', Lekhi said President Pranab Mukherjee was to be in Patna but cancelled his visit "owing to the rally".
"Had he come and such blasts occurred, what would have happened? Given the situation, JD(U) has no moral right to govern the state," she said.
