The Election Commission today rejected pleas of the Congress, the BJP and the Delhi government to implead as parties to a petition in the office of profit case that seeks disqualification of 21 AAP legislators for holding the post of parliamentary secretaries. <br/><br/>The next hearing will now be held on 10th of next month. But at the same time the poll body said, while it cannot allow the applicants to be joined as parties, it may seek their assistance as offered by them, if and when required.<br/><br/>Prashant Patel, who had petitioned before the Commission seeking disqualification of the MLAs, had opposed the plea of Congress and BJP of becoming a party to the case saying they wanted to politicise the issue. Congress and BJP had said that they should be allowed as parties as the issued involved public interest and money of the exchequer.
