"The Chief Minister's term was gripped in controversies and series of allegations, including the alleged murder of his party worker, Haji Mohammad Yusuf at his Gupkar residence," Congress spokesman Salman Nizami said in a statement here.
"Instead of resigning on moral grounds until enquiry, Omar preferred to hold the chair. Even the son of the deceased has charged Omar and his associates of torturing his father to death. This is a serious allegation and needs to be probed further," Nizami said.
The Congress spokesman also criticised Omar for "mishandling" 2010 situation, saying the Chief Minister was enjoying his holidays in Gulmarg when innocent people were getting killed in the state.
"As a result of his irresponsible approach, over 100 innocents got killed. He was running his government on Twitter and Facebook. He didn't even bother to visit the affected families to express condolences," Nizami said.
Terming the six-year rule of Omar Abdullah as the "darkest chapter" in the state's history, the Congress spokesman said that the NC working president was making baseless allegations after failing to hide his failures on all the fronts.
"Omar Abdullah's rule was the darkest chapter in the state's history. As Chief Minister, he has to take responsibility of all the wrong policies which his government adopted. He can't brush aside his failures by levelling false allegations against the Congress party," Nizami said.
The Chief Minister was always missing when the state was facing the crisis be it natural or manmade, he said.
"For lust of power, the NC leaders can go to any extent. Omar will not hesitate to join hands with BJP, whom he is bashing these days in his election rallies," he added.
Yousuf had died in Crime Branch custody on September 30, 2011. He was handed over to the Crime Branch by the Chief Minister at his official residence following allegations of political corruption.
