THE alarm bells have begun to ring at the Shiv Sena headquarters at Dadar. The downward slide of the Shiv Sena is a fact that even party leaders have begun taking serious cognizance of. Revolt is not all too often seen in a monolithic party like the Sena. But when Suresh Navle, the Sena minister of state for energy, made the startling allegation on the floor of the Vidhan Sabha that there was a complete breakdown of law and order in the alliance-ruled state, he took the treasury benches by surprise. Navles broadside against his own government came following threats made by "around 250 Sena goons" who barged into his bungalow situated just a stones throw away from the governments seat of power.
