"The withdrawal of the Interpol red corner notice against (Italian businessman) Ottavio Quattrocchi at the behest of the Central Bureau of Investigation (CBI) is another step to bury the Bofors gun case by the Manmohan Singh government," the CPI-M politburo said in a statement here.
"Coming in the wake of the failure to successfully prosecute all those involved in the bribery case, it is evident that as long as there is a Congress-led government in office, the subversion of justice will continue."
The CPI-M asked the Congress leadership to answer to the people for "this cover-up".
The 12-year Interpol Red Corner Notice, or lookout notice, for Quattrocchi was taken off from the wanted section of the CBI's website reportedly on the legal advice of Attorney General Milon Banerjee.
The CPI-M also welcomed the Supreme Court decision directing a Special Investigation Team (SIT) to investigate a complaint against Gujarat Chief Minister Narendra Modi and other cabinet ministers and top officials for their role in the Gujarat riots.
Describing the 2002 riots as state-sponsored pogroms, the CPI-M said: "It is a welcome step, though a belated one".
"It is now imperative that the SIT investigate the complaint and submit their conclusions within the three-month time-frame set by the court," the CPI-M said.
"It is shameful that the BJP continues to defend those responsible for the carnage in Gujarat," the politburo added.
The CPI-M welcomed the Sri Lankan government's decision to halt combat operations against the rebel Tamil Tigers using heavy weapons and airplanes. It also said: "The LTTE has to stop holding people by force and facilitate their safe passage."
"The Sri Lankan government should allow the International Red Cross and other agencies to enter the affected areas," the CPI-M said.
