New Delhi, Apr 23 (IANS): Samajwadi Party (SP) chief Mulayam Singh Yadav Tuesday said his party did not believe that the Congress-led central government has interfered with the CBI report on the coal block allocation scam.

Asked if his party believed that the United Progressive Alliance (UPA) government manipulated the CBI report on coal block allocation, Mulayam Singh said: "We do not believe so, but we believe that the government should give an explanation."

Talking to reporters at Parliament House, the SP chief also said that the coal block allocation scam was not the most important issue faced by the nation.

"China has occupied 12 km land along the border, that is a more serious issue. Why is media ignoring it?" he said.

Both the BJP and the Left parties have demanded Prime Minister Manmohan Singh's resignation over the alleged government interference in a Central Bureau of Investigation (CBI) report on the coal block allocation scam.
