Durga Shakti Nagpal, the IAS officer whose suspension has provoked a national debate, offered her defense today to the Uttar Pradesh government. Ms Nagpal, 28, met the state's Chief Secretary, Javed Usmani, and clarified that she had not endangered communal harmony by asking for a wall near an under-construction mosque to be demolished, as alleged by Chief Minister Akhilesh Yadav.
