NEW DELHI (Reuters) - Former Indian Prime Minister Manmohan Singh was summoned on Wednesday by a court accused of criminal conspiracy in an inquiry into the award of coal fields during his term, in a blow for the Gandhi dynasty that ruled India until last year.
A special court under federal law enforcment agency the Central Bureau of Investigation summoned the former prime minister along with billionaire Kumar Mangalam Birla and another official to appear on April 8, a source at the agency said.
Most coal block awards made by Dr Singh's government, which ran India for a decade, were overturned by the Supreme Court after it ruled the process illegal late last year.
"I am upset, but this is a part of life," Manmohan Singh told reporters on Wednesday.
"I am sure that the truth will prevail and I will get a chance to put forward my case with facts," Dr Singh was quoted by The Times of India as saying.
Prime Minister Narendra Modi's government, which ousted Dr Singh's Congress-led administration last May, is now in the process of re-auctioning the fields in a process key to reducing India's heavy dependence on coal imports.
The summons relates to a coal field allocated in 2005 to Hindalco Industries, part of the US$40 billion (S$55.5 billion) Aditya Birla Group. Mr Mangalam Birla is the chairman of the group. The company declined to comment.
Dr Singh is a globally respected economist credited with 1990s free-market reforms that unshackled India from its socialist past. He played a prominent role in managing the 2008 financial crisis.
He ruled as prime minister for a coalition led by the Gandhi dynasty's Congress party. His second term was mired in corruption scandals and accusations that party leader Soniua Gandhi called the shots in his government.
Dr Singh's image as a clean politician was damaged by the scale of corruption alleged to have taken place beneath him.
"The former government has absolutely nothing to hide. We conducted ourselves with utmost probity and transparency and the legal process will vindicate us," party spokesman Manish Tewari said.
