Congress has sought to address the Left concerns in the wake of the latest controversy in the Bofors case, with Sonia Gandhi [Images] telling them that the party-led coalition had no knowledge about the Central Bureau of Investigation decision to allow defreezing of Ottavio Quattrocchi's London [Images] bank accounts.

Asserting that the government was not pressurising any investigating agency, the United progressive Alliance chairperson told Communist Party of India-Marxist Politbureau member Sitaram Yechury that the Bofors case, which was dragging on for the past 20 years, should reach a conclusion soon, sources said.

Gandhi's clarification came in the wake of the CPI-M General Secretary Prakash Karat and RSP leader Abani Roy asking the government to explain why the decision to defreeze the Quattrocchi accounts was taken.

At an hour-long meeting Tuesday, Yechury told Gandhi that the Left parties would go ahead with their decision to protest the proposed visit of US President George Bush [Images]. The two leaders also discussed the phone tapping episode involving Samajwadi Party leader Amar Singh, with Gandhi telling the CPI-M leader that Congress would continue to support the Mulayam Singh government in Uttar Pradesh.
