The Lok Sabha today took up a discussion under rule 193 on alleged money laundering case involving Aircel-Maxis deal. The AIADMK members had raised the issue yesterday accusing former finance minister P Chidambaram's son Karti Chidambaram of investing huge wealth in different countries through his companies. <br/><br/>When the House reassembled at 12.30, the Speaker allowed discussion on the issue. Initiating the debate, BJD leader Bhartruhari Mahtab questioned the delay on the part of the present government agencies to file a charge sheet in the Aircel Maxis deal. Mr Mahtab urged the government to investigate thoroughly the money laundering allegation against former Finance minister's son.<br/><br/>AIADMK leader T G Venkatesh Babu said Aircel Maxis deal was materialised with the help of two former DMK union ministers during UPA rule. Mr Babu demanded a thorough probe by the CBI and ED to unearth this huge scam and prosecution of Mr Chidambaram and his son. <br/><br/>According to documents recovered in the recent joint raids carried by the Enforcement Directorate and Investigation Wing of Income Tax in relation to the Aircel-Maxis scam it was revealed that Karti Chidambaram has built a massive empire for himself through investments in real estate and other financial dealings across the world. Karti ?reportedly acquired a huge amount of wealth through his dealings between 2006-2014, when his father P Chidambaram was the Finance Minister and Home Minister. <br/><br/>Earlier, before the start of the discussion, Mallikarjun Kharge of Congress said the matter is sub judice so it should not be discussed. However, Parliamentary Affairs Minister M Venkaiah Naidu said the House has taken up many sub judice issues earlier too. While the discussion was on, Congress members continued to protest and later staged a walkout.
