Home Minister P Chidambaram, said a very comprehensive security plan has been drawn up for the the New Delhi Commonwealth Games in October 2010 .In an interview to an agency, MrChidambaram said the security personnel of the participating countries came to Delhi a few weeks ago and they were given a full presentation and they have expressed satisfaction with the plan. Security has been a major issue after the Mumbai terror attacks last November, which led to the abrupt end to theone-day series between India and England and the postponement of the inaugural Champions League.Australia's Commonwealth Games chief Perry Crosswhite had earlier this month raised concerns about security in Delhi and had said that he could not guarantee safety of his country's athletes.
