Hitting back at Congress President Sonia Gandhi, former External Minister K Natwar Singh today said she was behind his recent problems with the Enforcement Directorate in the Iraqi oil-for-food scam and attacked her foreign origins.Singh fears that he and his family might be jailed and harm can come to his family members including his grandson."Everything that the government did against me was on Sonia's direction. I will not blame (Prime Minister) Manmohan Singh," he told Star News, a release issued by the channel said.The charges by the 75-year-old career diplomat-turned- politician, a Nehru-Gandhi family loyalist for long, comes close on the heels of Gandhi's attack on him in a TV interview three days ago.Singh was apparently referring to the setting up of an inquiry authority to go into allegations against him and his son in the wake of their names figuring in the Volker report on the oil-for-food scam and the ED questioning them in this connection.Reacting to Gandhi's accusation of her being betrayed by Singh, he said, "Betrayed is a strong word and according to Indian culture such words are not used for a person older than her 15 years." He also said, "Those who are born in Indian soil will only understand the country's ethos and culture. Others will not."Singh quit as External Affairs Minister in November last year and was suspended by the Congress from its primary membership in August this year for bringing "disrepute" to the party.
