Bringing to fore rift with its ally after fracas over book launch of former Pakistan Foreign Minister Khurshid Mahmud Kasuri here, Shiv Sena today asked BJP to opt out of the coalition government in Maharashtra if the latter was bored of its brand of "nationalism" and "patriotism."

Adopting an aggressive posture vis-a-vis BJP, Sena attacked its senior ruling alliance partner, bringing to fore fissures in the alliance between the two parties, which parted ways ahead of Assembly polls in Maharashtra last year, but later came together to share power.
