As the debate over reservation for minorities escalated yesterday.The Election Commission put on hold the Congress Party-led government's decision to carve out a reservation sub-quota for minorities till voting in five poll-bound states is completed. The EC's order comes a day after it issued a show-cause notice to Law Minister Salman Khurshid, following a complaint from the BJP, for promising to double the quota for minorities to nine per cent. The government maintains its move on sub-quotas for minorities was not aimed at any specific religious group while the BJP claims vindication with the Election Commission's order.
