MUMBAI - The politician son of the Indian president has been asked to explain the origins of 10 million rupees ($203,000) found in a party worker’s car in his constituency, an official said Friday. The money was discovered by police during patrols in Amravati district in the western state of Maharashtra earlier this week ahead of local elections which took place on Thursday. The district is the state assembly constituency of Raosaheb Shekhawat, son of India’s president Pratibha Patil, who is a leader of the local Congress party, which rules both the state government and nationally in New Delhi.
