New Delhi, Oct 28 (ANI): The opposition on Monday lashed out at Union Home Minister Sushil Kumar Shinde for enjoying the music launch of upcoming film ‘Rajjo’ in Mumbai on the day when Patna was rocked by serial blasts. The opposition used the occasion to target the ruling Congress Party, saying all their leaders are busy in such things rather than devoting their time on issues of national interest. Shinde attended the function hours after serial blasts rocked Bihar's Patna city ahead of BJP's prime Ministerial candidate Narendra Modi's 'Hunkar rally'.
