Jagan Mohan Reddy, who has named his party the YSR Congress after his father, will be interrogated by the CBI tomorrow about alleged corruption and the funding of his vast business empire. Mr Reddy's father, YSR Reddy, died as chief minister in 2009 in a helicopter crash. Mr Reddy believes that the CBI is being used by political parties to ensure he is arrested ahead of June, when 18 critical by-elections are being held in Andhra Pradesh.
