Turning on heat on activist-turned-politician Arvind Kejriwal on Saturday, Congress general secretary Digvijaya Singh posed 27 questions to him over a range of issues, including his alleged violation of service rules as an I-T officer, foreign funding of his NGO and its ties with international NGOs, such as Avaaz, and property deals by his associates.

IAC leader Manish Sisodia said all answers were already available with the PMO.

In a letter to Kejriwal, Singh wanted to know if IAC coordinator Mayank Gandhi is involved in real estate projects and the quantum of funds he contributed to the organisation. Kejriwal also accused Singh of spreading lies about him wishing to become an NAC member.
